with the summit prominent, truncated and rectangular below, the lateral 

 margins barely sinuated, clypeus longer, acutely triangular. Pronotum

 others exterior to these ; mesonotum sub-semicircular, broad triangular 

 apically, raised above the level of the head, feebly convex, stained on the 

 forward border, with a large black spot at each outer angle and with two 

 dots on the middle and two at base ; middle of scutellar portion also with 

 a black dot. Hemelytra ample, obliquelv decumbent, marked as above 

 recorded, the costal field wide, rounded and expanded near the base, the 

 diagonal veins numerous, longitudinal veins of the membrane sometimes 

 dusky. Beneath and legs pale testaceous, or white with a tinge of green.

D. acuta, new sp. 



Pale dull testaceous with a tinge of gray or olive, robust, with ample 

 hemelytra. Head bluntly triangular, hardly longer than the pronotum, 

 with the lateral margins of the vertex oblique, a little curved and followed 

 inwards by a deep, long depression; front polished, longer than wide, 

 curving a Jittle narrower below, the margins strongly reflexed and bounded 

 inwards by a groove, the summit made prominent by a rounded dark 

 callosity, clypeus longer than wide, acutely narrowing, obsoletely cari- 

 nated on the middle. Pronotum crescentic, strongly arcuated, the narrow 

 ing sides curved back beyond the limit of the eye, indented each side of 

 the middle; mesonotum prominently i-aised, the dorsal shield oval, nearly 

 twice as long as wide, carinated on the margins and middle line, the sides 

 exterior to the shield convexly declining. Hemelytra wide, steeply de 

 clining, bluntly rounded, the costal area broad, with the humeral end promi 

 nent, and with two series of black dots, the cross-veins coarse, brownish, 

 distinct, mostly simple, somewhat reticulate at base on the basal portion; 

 disk with two approximate, brown, dagger-shaped marks, the surface 

 with remote, small, black dots. Cuneus with rows of punctures at base, and 

 acute granules toward the tip. Veins of membrane brown, submargin 

 of the apical areoles with a series of brown dots. Wings pale testaceous, 

 with the veins whitish. Legs dull pale testaceous, with the tarsi more" 

 or less dusky, and the nails brownish. Venter yellowish white, pulveru 

 lent, last segment narrowly bordered each side with black. The hemely 

 tra are sometimes spotted with brown at intervals on the costal area and 

 disk, and a series of interrupted brown lines is conspicuous next the 

 inner margin of the cuneus, while the veins are variable in the extent of 

 embrownment. Two pale brownish spots are sometimes present on each
