Uitn pale brown or tawny yellow. In fully colored examples the former has 

 a blotch behind the eyes and the basal angles of the latter are brown, fre- 

 quently these marks are absent and the apex of the scutellum may be fulvous 

 like the vertex. In this form the elytra are more distinctly marked than in 

 pulicarius. On the corium are two semipellucid spots at base and about 

 six at apex, more or less coalescent ; an oval spot on the base of the anti- 

 apical areoles and two more, sometimes forming a band before the middle, 

 are whitish. Wings milky with the nervures at apex brown as in the pre- 

 ceding species. Abdomen brown with the convexivum, edge of the tergum, 

 apical half of the last ventral segment and narrow margin of the others, 

 pale. Genital characters as in pulicarius. Length y/z mm. 



New York. Of this species I have taken one male and four 

 female examples at Lancaster, N. Y., in August and September 

 in company with the preceding of which it may prove but 

 a variety. 



17. XESTOCEPHALUS TESSELLATUS, n. sp. 



Pale testaceous. Vertex with dark-brown irrorations which become 

 aggregated either side of the middle; ocelli placed on large pale dots; face 

 brown irrorated with pale in the female, or pale and nearly immaculate in 

 the male. Pronotum testaceous-brown, darker on the disc, irregularly irro- 

 rated with pale and marked with a blackish spot behind the inner angle of 

 the eye. Scutellum pale brown, obsolete'}- dotted with paler, the basal 

 angles and sometimes a line between them partly covered by the pronotum, 

 blackish; the apex pale. Elytra testaceous, the nervures alternated with 

 dark brown and white ; a mark on the base of the clavus, two quadrate spots 

 on the costa including two dots between them, blackish; apex of the elytra 

 paler marked with four large squarish, brown marginal spots. Wings white 

 with pale brown nervures. Disc of the tergum, base of the venter and some 

 clouds on the pleural pieces brown. Apical margin of the last ventral seg- 

 ment of the female feebly concave and minutely notched at the middle; 

 pygofers proportionately a little shorter than in pulicarius and the plates 

 of the male are more strongly narrowed from near the base to a slender 

 point. Valve concealed. Length 4 mm. 



Charlotte Harbor, Florida, Mrs. Annie Trumbull Slosson; 

 Mississippi, Howard Ewarts Weed; Texas, "Aaron." Descri- 

 bed from one male and four female specimens. This species is 

 larger than the foregoing and may be distinguished by its irro- 

 rated vertex and pronotum, the blackish basal angles of the 

 scutellum, the testaceous elytra marked with large marginal 

 brown spots, and the varigated elytral nervures. Most of the 

 specimens show a large oval white pruinose spot on the middle 

 of the costal margin of the elytra, but this may be characteristic 

 only of the breeding season.
