COLGANTA NIGRO-MACULATA, Sp. DOV. 



Lutea, antennis nigris, flagello late albo annulato ; mesonoto, 

 femoribus, tibiis tarsisque posticis nigris ; alis fulvo-hyalinis ; nervis 

 stigmateque nigris. ? . Long, 15 mm. ; terebra, fere 3 mm. 



Hah. Sarawak, Borneo {Shelf ord). 



Autennse black, the sixth to nineteenth joints white. Head luteous ; 

 the vertex broadly in the middle and the greater part of the occiput 

 black ; the face is wrinkled in the centre ; the sides bear large round 

 clearly separated punctures ; the mandibles are broadly black at the 

 base. Thorax luteous, the sides paler in tint ; the mesonotum and the 

 sides of the median segment at the base black ; the mesonotum is 

 closely punctured ; the scutellum is thickly covered with long black 

 hair ; the scutellum is keeled to near the apex. The median segment 

 is wrinkled ; the basal keels are straight at the base ; the rest of them 

 are irregularly twisted and curved towards the edges of the segments, 

 where they join a straight lateral outer keel, a large enclosed area being 

 thus formed, which is about twice longer than broad. Propleurse 

 punctured above, the middle obliquely striated. Mesopleurfe smooth 

 and shining ; the metapleurae with the lower apical part stoutly 

 obliquely striated. The four front legs are coloured like the body, 

 with the middle femora darker above ; the hind legs black ; the coxae 

 and the basal joint of the trochanters luteous ; the coxaB are marked 

 with black at the apex above. The apex of the petiole and the other 

 abdommal segments are for the greater part fuscous-black above. 



CoLGANTA RUFIPES, Sp. IIOV. 



Nigra ; pedibus rufis ; tibiis posticis nigris ; alis fulvo-hyalinis. $ . 

 Long. 15 mm. ; terebra, 4 mm. 



Hah. Borneo. 



Antennse black, the eighth to seventeenth joints white beneath ; the 

 apical joints brownish. The face roundly projects in the middle, and 

 is there closely but not strongly punctured ; the sides bear large deep 

 punctures, and are irregularly striated on the inner side ; the malar 

 space is brownish ; on the lower inner orbits is a pale yellowish mark. 

 Mesonotum and scutellum closely punctured ; the apex of the scutellum 

 and the post-scutellum pale testaceous. The base of the median seg- 

 ment is closely punctured and irregularly striated ; the middle of the 

 apical slope of the segment is closely, irregularly striated ; the sides 

 are coarsely, irregularly reticulated ; the lower outer part bears four 

 stout keels, and is bordered by keels on either side. The lower half of 

 the propleurse is stoutly keeled ; the mesopleurfe almost smooth; the 

 metapleurte closely, obliquely striated on the apical half. Legs rufous ; 

 the apex of the hinder femora, the tibi^, and the base of the hinder 

 tarsi black ; the rest of the hinder tarsi white. Abdomen black ; the 

 apical two segments white above. 



This genus is probably well represented in Northern India. 

 The species known to me from the Khasia Hills may readily be 

 recognized by the following table. They are all fulvous or 

 ferruginous in colour.
