SYNONYMICAL AND DESCRIPTIVE NOTES ON NORTH 

 AMERICAN HETEROPTERA.

Thyreocoris pulicarius, Germar. 



Dr. Distant has very kindly compared for me specimens of our 

 northern and southern forms of this insect with the type of Corimelcena 

 margine/la, Dallas, and assures me that that species is identical with our 

 smaller southern form, and he agrees with me in placing this under the 

 name pulicarius, Germar. Whether our larger northern form is a distinct 

 species or merely a variation of pulicarius is a question on which I am 

 still in doubt. 



Brochymena Harrisii, Uhler. 



An examination of Uhler's type in the Harris collection shows this 10 

 be a synonym of annu/ata, Fabr. Dr. Uhler's identification of annu/ata, 

 published in connection with his description of Hariisii, really refers to 

 4-pustulata, Fabr., as pointed out by me in my Annotated Catalogue of 

 our North American Pentatomidte. This leaves without a name the species 

 cited by me as Harrisii in the paper above mentioned, which I now de- 

 cribe as 



Brochymena punctata, n. sp. 



Brochymena Harrisii, Van D., Trans. Am. Ent. Soc, XXX, p. 31, 

 1904. 



Smaller than anuulata, with the head more truncated at apex ; 

 pronotum, scutellum and elytra distinctly dotted with smooth white points. 

 Length, 14-15 mm. 



Apex of the head very obtusely angled, almost truncated, the inner 

 angle of the cheeks scarcely meeting over the apex of the tylus. First 

 antennal joint almost attaining the tip of the head, second and third 

 respectively longer, the fourth equal to the third. Pronotum hardly as 

 wide as in annu/ata; the humeri less produced, and the anterior lobe 

 with coarser and more irregular denticulations ; the posterior lobe quite 

 distinctly denticulate on the latero-anterior margin ; the surface closely 

 and quite regularly punctured with fuscous on a whitish ground ; anteriorly 

 with the dark punctures segregated along the submargins and in two oval 

 patches at the inner angles of the callosities ; the median line carinate 

 and smooth anteriorly. Scutellum shorter and more rounded at apex than 

 in annu/ata, punctured with blackish on a pale ground, and marked with
