C. fuscus: Clypeus, much concave. Colour, from brown to yellowish brown. Body length, 5-7mm. Abdomen spots, two pairs and spots on the second segment not overlap with first segment.

C. quadrinotatus: Clypeus, a little concave. Colour, black all over. Body length, 3-5mm. Abdomen spots, two pairs and spots on the second segment overlap with the first segment.

Worker
C1= 100.00, SI 1=80.00, SI 2 -80.00, EW 0.2683, EL 0.·1<177, HW = 1.79, III = 1.79, SL = 1.43.

Head vary from yellow to brown, with minute dense punctures all over and head length same as head width. Mandibles brown and lustrous, with rough punctures. Teeth dark black and five and short, but sharp. Long curved yellow hairs present on the end of each tooth. Clypeus yellow and lustrous, with abundant minute punctures. Clypeus protruded totally and anterior area of clypeus concave, but it looks like a cut slope in ventral view and a long erect hair present on the middle area. Separated line between clypeus and frontal triangle indistinct. Frons vary from yellow to dark brown, with abundant dense minute punctures. Vertex with minute punctures all over. Ocelli absent. Posterior marginal line nearly straight.

Compound eyes dark grey and almost not protruded outward and width 0.60 times as length. Antennal fossae comparatively large and two third of base of scape naked. Scape yellowish brown, with abundant pubescences. Antennal scape extending a little backward as far as posterior marginal area of head and 0.8 times as head length. Five or more erect hairs present on the base of funiculus. Funiculus eleven segmented and erect hairs absent in each segment, but minute recumbent hairs present abundantly.

Pronotum light yellowish brown, with minute punctures and abundant pubescences, without any erect hairs. The groove between pronotum and mesonotum and the groove between pronotum and episternum distinct. Pronotum dark brown and a pair of erect hairs presents on the top. The groove between mesonotum and metanotum and the groove medonotum and propodeum indistinct. Propodeum dark brown and slope bended much. Propodeal spiracles elliptical. with a pair of long erect hairs. Petiole dark yellowish brown and scale form, with long yellowish brown erect hairs on the top.

Abdomen five segmented, with long sharp erect hairs on the posterior marginal area of each segment, but sparesly distributed on the middle area of each segment. A pair of white spots presents on the first segment and on the second segment among four white spots. Never the spots on the second segment meet the first segment.
