disk blackish, the anterior and posterior margins narrowly bordered 

 with red, the posterior angles acute. Scutellum black. Elytra 'lull 

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

 i . the intervals roughly punctured, bul with no distinct reticu- 

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



$ . Rostrum long and slender. Antennae a trifle shorter than in 

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

 aded, the side- rectilinear, the posterior angles a little less than 

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

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



The tv. mens above described as sexes are very dissimilar, 



bid they have so much in common, besidos the peculiar rusty-red 

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

Hub. JSouth India ( Walhouse). 



Very close to L. modestus, but differs in having no black on the 

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

 finer and without reticulation.

Parallel. Bostrum rather long, yellowish red. Antennas mode- 

 rat ely 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.
