Dark castaneous, legs and antennae a little paler. Dorsal and 

 lateral outlines as in Figures 1 and 13. Front margin of vertex 

 slightly emarginate medially and slightly concave laterally. Head 

 impunctate, but remainder of upper surface provided with numerous 

 shallow and almost evenly distributed punctures. Scutellura dis- 

 tinctly constricted all the v/ay across near anterior margin. Prop- 

 leurum punctate uniformly w^ith remainder of pleural surface. 

 Length, 1.5 mm. ; width, 1 mm.

MEGARIS NIGRITULA Stal 



Cyi'taspis niffritula, Stal, C, (In part) Biclrag till Rio Janeiro-traktens 

 Hemipter-Fauna, vol. 1, 1860, p. 9 [Brazil]. 



There are two specimens in the type material, w^hich, although male 

 and female and possibly of the same species, must in the present state 

 of knowledge of the genus be treated as two species. The female 

 specimen is selected as holotype, because it is labeled Rio and is 

 therefore from the area treated in the memoir in which the original 

 description was published, and the length (2.5 mm.) agrees better 

 with the original statement. 



Black; antennae and legs distally, paler. Front margin of vertex 

 truncate medially, concave laterally, upper surface wrinkled and 

 shallowly punctate except on occiput; pronotum except callosities 

 finely and irregularly transversely wrinkled and punctate, and with 

 fine rastration posteriorly; scutellum conspicuously wrinkled and 

 punctate throughout peripheral areas, less markedly so on disk; 

 clavus punctate; pleura entirel}?^ punctate, propleura less copiously 

 so; sternites impunctate even along incisures, 6 broadly rounded 

 anteriorlj'-, all of the others more or less shortened medially ; genital 

 plates transverse, punctate, almost oblong in shape. 



Holotype. — Female, Bio de Janeiro, January (Stockholm Mus.).

Gyrtaspis punctulata Hokvath, G., Analec.ta ad cognitionem Cydnidarum, 

 Ann. Mus. Nat. Hung., 1919, p. 209 [Trinidad]. 



Dark castaneous. Form hemispherical; front margin of vertex 

 slightly angulate-emarginate medially, then convex on each side to 

 eyes, disk moderately punctate ; pronotum except callosities and pos- 

 terior disk, and scutellum almost entirely, copiously and distinctly 

 punctate; pleura punctate throughout, the propleura less copiously 

 so; sternites punctate along anterior margins. Length 2 mm.
