disk blackish, the anterior aud posterior margins narrowly bordered 

 with red, the posterior angles acute. Scutellum black. Elytra dull 

 red, gradually widening to near the apex ; each elytron with four 

 costae, the intervals roughly punctured, but with no distinct reticu- 

 lation. Margins of the abdominal segments dull brick-red. 



5 . Rostrum long and slender. Antennae a triHe shorter than in 

 the male. Thorax very broad, the margins broadly reflexed and 

 expanded, the sides rectilinear, the posterior angles a little less than 

 right angles, the disk more or less blackish. Elytra dull red. Ab- 

 domen duU brick-red, blackish in the middle at the base. 



The two specimens above described as sexes are very dissimilar, 

 but they have so much in common, besides the peculiar rusty-red 

 colour, that there is little doubt that they should be associated as 

 sexes.

 Hub. South India ( Walhouse). 



Very close to L. modestus, but difi^ers in having no black on the 

 elytra near the scuteUum, and the sculpture of the elytra is much 

 finer and without reticulation. 



Lycostomus rufiventris. 



(Plate III. fig. 2.) 



Fusco-niger, opacus ; thoracis limbo, antennarum articulis tribus 

 basalibus, abdomine elytrisque ferrugineo-rufis, his apice nigris. 



Long. 7 lin., lat. 3 lin.

Parallel. Rostrum rather long, yellowish red. Antennae mode- 

 rately long and slender, gradually tapering from the fourth joint; the 

 first three joints pale red. Thorax somewhat trapeziform, a little 

 narrowed in front, pale red ; the disk black ; the margins broadly 

 reflexed, the sides rectilinear, the posterior angles a little less than 

 right angles. Scutellum red. Elytra somewhat parallel, rather pale 

 red. Coxae and abdomen reddish. 



With the specimens above described are associated two other 

 examples, which have the rostrum black, but do not differ mate- 

 rially in any other respect, and may therefore safely be considered 

 varieties.
