246 Mr. G. W. Kirkaldy's Memoir iqwn the 



The genus OriJiotylus has a wide range, viz., tlie wliole 

 pala^arctic region (except Japan and China), New Guinea, 

 Australia, St. Helena, Hawaiian Group and North America, 

 and is doubtless even still more widely extended. 



Diocoris, gen. no v. 



Closely allied to Z.vmocoris, Renter, but with longer head, 

 eyes very long, pronotum not strongly narrowed anteriorly. 

 Female macropterous with unialbosignate elytra. 



Elongate ; head almost vertical, elongate, § longer than high, 

 acutangiilar apically (profile). Vertex broad, nearly 3 times as wide 

 as an eye, acutely triangular infrontof the eyes (vertical), base finely 

 but distinctly sinuately marginate ; antenme about as long as entire 

 body. Eyes quite half the length of head (seen in jsrofile), distinctly 

 sinuate laterally, contiguous with pronotum, extending laterally 

 farther than anterior lobe of pronotum. Eostrum reaching a little 

 beyond base of posterior coxae, first segment not reaching to base of 

 head, three apical subequal in length to one another, Pronotum 

 declivous, anteriorly not strongly narrowed, lateral margins of 

 anterior half parallel, posterior half not greatly divergent, base con- 

 versely sinuate, exposing anterior part of scutellum, about f wider 

 than apical margin (of pronotum) ; pronotum about 3 times as long 

 as the eye (as seen from above). Collar distinctly separated from 

 pronotum by a very narrow suture, but not at all constricted. Elytra 

 reaching beyond apex of abdomen, sinuately emarginatc laterally, 

 unialbosignate ; cuneus not (or scarcely) declivous. 9 macropterous. 

 Abdomen strongly constricted at the base. 



2. D. agelastus, sp. nov. 



Covered with exceedingly short close velvety pubescence of the 

 general ground colour, not long pilose, punctured nor rugose. Very 

 dark chocolate with a purple tint (a little browner on vertex), pro- 

 notum and scutellum purplish-black. Antenna) dark brown, apical 

 2 segments covered with dense pale pubescence. Eyes stramineous. 

 A central transverse band on cerium, narrowing on entering the 

 clavus, which it traverses (also lateral margins of elytra very 

 narrowly)- — whitish. Membrane dark fumate, semiopaque, nervures 

 biownish-black. Pronotum about 2\ times as long as 1st segment of 

 antennse, which is about half the length of the head (profile) ; 2nd 

 segment nearly 3 times as long as 1st (f longer than pronotum), 

 subequal to the 3rd, which is ^ longer than the 4th. 



Lonji. 5 mill.
