66. Lygasus albulus Distant. 



At Crescent City I took two examples of what I believe 

 may be a dark form of this species, The typical albulus as I 

 identify it, I have taken at Denver and Ft. Collins, Colorado, 

 and have received others from Prof. Wickham that were taken 

 at Marysville, Utah. The western specimens have the elytra 

 dark rufous brown with their margins paler. The present 

 examples from Florida have the elytra almost black with most 

 of the costa and the scutellar margins rufous. In all the basal 

 angle of the membrane is deep black followed by a conspicuous 

 white mark, and a smaller one adjoins the tip of the corium. 

 Dr. Uhler's description of Lygceosoma solida agrees very closely 

 with this species. 



67. Nysius calif ornicus Stal. 



Abundant everywhere I collected in Florida. 



68. Belonochilus koreshanus n. sp. 



Smaller and darker than numenius. Head more slender anteriorly, 

 the tylus being a little more produced and exceeding the cheeks by at least 

 its own width; ocelli placed distinctly nearer together than in the allied 

 species; scarcely more distant from one another than from the eye. Buccu- 

 las distinctly elevated as far as the base of the antennae where they become 

 evanescent. Second joint of the antennas hardly longer than the third, 

 slightly clavate at tip. Scutellum a little longer than in numenius. Hind 

 margin of the corium almost straight, scarcely angled at the discal nervure. 

 Anterior femora unarmed. Rostrum normally reaching nearly to the apex 

 of the sixth ventral segment; sometimes shorter, in one specimen not sur- 

 passing the fourth segment. Color clear cinerous or slightly tinged with 

 fulvous; head, pronotum, scutelum and pectus coarsely and deeply punctured 

 with brown or fuscous. Antennas rufous, first joint and extreme tip of the 

 second and third grey, an annulus on the first joint, the clavate apex of the 

 second joint and the apical joint dark brown or blackish, the latter paler at 

 tip; a cloud about the ocelli extended as a smooth line interior to the eye, 

 transverse incised line on the pronotum, narrow smooth basal margins of 

 the scutellum, mesosternum, median line and apex of the rostrum, about 

 two lines of obscure linear marks on each side of the pectus and the tips of 

 the tarsi black; a line on either side of the tylus at base, an oblique mark 

 near the inner angle of the eye, two vittas before the antennas, the inferior 

 obscurely extended along either side of the rostral canal, a few marks on 

 the elytral nervures, a broken vitta along the middle of the membrane, the 

 disk of the venter and sometimes a few marginal or submarginal points, 

 fuscous or blackish. Membrane whitish hyaline. Tergum black with the 

 middle line and connexivum broadly castaneous, the margins of the latter 

 pale interrupted with black; margin of the coxal cavities and the thickened
