Hah. Ceylou ; Pundahioya (G^r€(?w). 



Found on wet rocks by running water {E. E. Green). 



Genus HELEOCOEIS. 



Heleocoris, Stdl, En. Hem. \, pp. 142 & 146 (1876) ; Montand. 

 Verh. z.-b. Ges. Wien, xlvii, p. 436 (1897). 



Type, H. ohliquatus, Spin.* 



Histi'ibution. Very widely distributed ; at present recorded from 

 all the principal zoological regions excepting the Nearctic and 

 Australasian. 



This genus is to be primarily separated from the preceding one 

 {Diapliorocons) by the structure of the eyes, which are subparallel 

 and slightly converging anteriorly ; disk of the prouotum regidarly 

 and uniformly convex ; connexivum posteriorly visible; the corium 

 a little obliquely narrowed from above middle to apex ; membrane 

 small.

 p. 372 (1887) : id. Verh. z.-b. Ges. Wien, xlvii, p. 447 (1897). 



Head and pronotum fuscous ; three spots on anterior margin 

 of head, the process beyond eyes, 

 and the lateral margins ot the pro- 

 notum more or less ochraceous, the 

 last with some small fuscous spots ; 

 hemelytra and scutellum piceous, basal 

 lateral margin of corium and exposed 

 connexivum ochraceous ; body beneath 

 and legs ochraceous, a spot on each side 

 of head beneath piceous ; abdomen 

 brovvnish-ochraceous, lateral margins of 

 the hemelytra abruptly and strongly 

 sinuate behind the embolium, where it is 



Y\g.\9.— Heleocoris strahiis. truncately cut ; lateral posterior angles 

 of the pi'onotum obliquely truncate ; 



eyes anteriorly converging their whole length ; claval suture as 



long as the scutellum. 

 Length 11 millim. 

 Hah. Tenasserim ; Thagata {Fea). 

 Montandon's type, by the courtesy of Dr. Gestro, is here figured. 



1503. Heleocoris breviceps, 3Iontand. Ann. Sac Ent. Eel;/, xli, p. 55 

 (1897) ; id. Verh. z.-b. Ges. Wien, xlvii, p. 447 (1897). 



Body oval in form, widened at middle and about equally 

 attenuated both anteriorly and posteriorly; yellow, with brown 



* Stal made H. ohliquatus, Spin., the type of his genus, from a specimen he 

 thiis identified in the collection of Signoret. Montandou, who has since 

 examined this specimen, doubts its being Spinola's species. In that case I 

 would propose that H. strabus, Montand., be considered the type of Heleocoris.
