the moderately prominent eyes, antenniferous tubercles produced 

 in an acute tooth, first joint of antennae shortly oval, reaching 

 apex of head, second a little longer than first, thickened from 

 base to apex (the other joints wanting) , bucculse short and low, 

 rostrum not quite reaching posterior margin of presternum, first 

 joint reaching anterior margin of eyes, second a little longer 

 than first, third slightly shorter than first, fourth as long as 

 second. Pronotum a little convex, without a distinct transverse 

 impression, roundedly narrowing from base to apex, about three 

 times broader at base than at apex, basal margin straight in 

 front of scutellum, shortly sublobately produced over base of 

 corium. Scutellum much broader than long, almost right-angled 

 at apex, the disk with a T-shaped carination. Elytra much 

 narrower than abdomen, corium and clavus impunctate excepting 

 a row of punctures on each side of the veins, rimula straight, 

 rather deeply impressed, forming an angle with the radial vein 

 and ending a little behind middle of mesocorium, apical angle 

 of corium narrowly rounded, apical margin obtuse-angularly sinu- 

 ate in its interior portion, claval commissure as long as scutellum, 

 membrane a little longer than corium, with five straight simple 

 veins, the two inner ones joined a little before their common 

 end. Front acetabula closed behind. Abdomen much broader 

 than pronotum, oval with rounded sides, last dorsal segment 

 about twice the length of the preceding segment, connexivum 

 broad, its greatest part not covered by the elytra. Fore coxse 

 not nearly reaching posterior margin of presternum; femora 

 elongately subclavate, the fore and middle pair beneath near 

 apex armed with a few very minute teeth; fore tibite slightly 

 shorter than femora; first joint of hind tarsi as long as third, 

 second extremely small. 



Distinguished from all other genera of this subfamily by the 

 broad oval abdomen ; to be placed between Ischnodemus Fieb. 

 and Blissus Klug, differing from the former by the sinuate apical 

 margin of the corium, from the latter by the posteriorly closed 

 fore acetabula. 



Type of the genus, Anisosoma lativentris sp. nov. 



Anisosoma lativentris sp. nov. 



Black, disk of venter fuscous, elytra dingy grayish white, the 

 punctures and veins of membrane a little darker, base of clavus 

 a little infuscated, abdomen above and lateral borders of venter 

 dingy ochraceous, rostrum (except the fuscous apical joint) and 

 tarsi testaceous. Head half the length of pronotum, extremely 

 finely punctate. Pronotum slightly broader than long, thickly
