6 NOTES ON JAMAICAN HEMIPTERA 



are rather smaller than the smallest tibialis and pulicaria. I 

 have followed Dr. Oshanin in using this generic name in place 

 of Corimelama. 

 Thyreocoris cognatus n. sp. 



Very near pulicaria from which it may best be distinguished by a 

 comparative description. A little smaller and somewhat more elongated, 

 punctures coarser and deeper over the whole surface. Head distinctly 

 longer and more narrowed anteriorly. On the pronotun the callousities are 

 more conspicuous as smooth slightly elevated surfaces and there is a slight 

 trace of a longitudinal median line ; the carinate lateral edge is continued 

 around beneath the feebly elevated humeri, not conspicuously interrupted 

 beneath the prominent gibbous humeri as in pulicaria. The antennae are 

 more slender and with the tibiae and tarsi are paler; the pale margin of the 

 corium is more distinctly punctate ; the posterior margin of the scutellum 

 is pale in all the specimens before me, and the margin of the connexivum 

 posteriorly is marked with about three pale points in place of the pale line 

 [sometimes broken] found in pulicaria. The genital segment of the male is 

 a little longer and narrower with the sides more oblique than in pulicaria. 



Described from numerous specimens taken at Rock Fort 

 near Kingston. From tibialis this species differs in being pro- 

 portionately longer and narrower, with a longer head and more 

 closely puncttired surface. The corium is pale with no indi- 

 cation of a black costal streak. 

 Thyreocoris basalis Germar. 



Of this well marked species I took several examples at 

 Balaclava, and found them not uncommon on weeds along the 

 roadside at Richmond. 



Family Scutelleridae 



Diolcus irroratus Fabr. 



I took large numbers of this insect at Rock Fort on a coarse 

 almost shrubby weed that has much the appearance of a Cheno- 

 podium, in the spiny angular bracts of which these insects were 

 well concealed. I also took it near the Constant Spring Hotel, 

 and at Mandeville and Montego Bay. In this species as in our 

 northern Eurygaster alternatus the males were very uniformly 

 punctured or obscurely mottled while the females were strongly 

 marked. Prof. Ball has sent me a fine series of this insect 

 taken on Hayti where it seems to be as abundant as in Jamaica.: 

 Homoemus proteus Stal. 



I took single examples joi this species near the Constant 

 Spring Hotel, at Balaclava, Montego Bay and Richmond.
