median impression longitudinally divided by a keel. Metasternum 

 with the pleurae divided by two longitudinal keels, inner keel some- 

 what curved, inner area of pleurae transversely rugose. Hemelytra 

 reaching apex of abdomen, opague, corium besides the hairs with 

 narrow ochraceous scales arranged in two or three longitudinal rows, 

 the epipleura with similar scales, apical angle of corium truncate, 

 inner basal cell of membrane scarcely reaching middle of outer basal 

 cell. Abdomen somewhat broader than pronotum, connexivum near 

 outer margin with decumbent hairs and with a long semierect hair 

 at the somewhat prominent apical angle of the segments, venter with 

 the flat discal area much narrower than the rather strongly ascending 

 lateral areas, basal margin of the segments strongly crenulte within 

 the flattened area, sixth segment of female in the middle a little 

 longer than the two preceding segments united. Fore legs with the 

 trochanters setose, femora rather strongly incrassated. Middle legs 

 more separated from each other than the hind legs. 



Length. — Female 7 mm.

Allied to H. moUis Breddin (which I know only from the rather 

 short description), but lacking the long, soft, decumbent pilosity, dif- 

 ferently colored, and with the adventitious jointlet between the first 

 and second antennal joints much shorter. The other Imown species, 

 H. disci^etus^ var? (of which I have examined a cotype), differs from 

 corticalis by numerous characters, and principally by the much 

 larger size, the more depressed body, the more tumid anterior acetab- 

 ula which are visible from above, the acute apical angle of the 

 corium, the longer inner basal cell of the membrane w^hich passes 

 the middle of the outer basal cell, and the much less strongly ascend- 

 ing lateral areas of the venter. As the genus has been somewiiat 

 imperfectly described, I have included some generic characters in 

 the above description, but the peculiar carinated sculpture of the 

 venter is not mentioned, as it was described by me.* Breddin's sup- 

 position 2 that this sculpture is a male sexual character does not 

 prove to be correct, the ventral sculpture of the now discovered 

 female being quite identical with that of the male. 



The species of this genus doubtless live under bark like the other 

 Reduviinae with flattened abdomen. 



The genus Heteropinus Breddin was placed by its founder near 

 Opinus Laporte, and the allied genus Platymicrus Bergroth was also 

 placed by me near Opinus., but we were both wrong in so placing 

 them. Although the small setiferous tubercles on the underside of
