224 University of California PuUicatiom. [Entomology 



Described from six females from southern California. I took 

 it at Alpine, San Diego County, in June, and ]\Ir. Fordyce 

 Grinnell has sent me specimens taken at Pasadena, June, Los 

 Angeles, September, and from the Santa Rosa Mountains. 



Pseudopsallus n. gen. 



Aspect of Plagiognatlius nearly, but having cell of wing with- 

 out a hamus and arolia free and connivent. Body clothed with 

 long black hairs and short, appressed, silvery scale-like hairs or 

 tomentum, which soon wear off, leaving the insect smooth. 



Head broad and short, vertical. Vertex with an oblique 

 impression either side, leaving the base prominent but hardly 

 carinate. Front moderately convex, perpendicular or nearly so. 

 Clypeus broad, somewhat prominent, but little compressed; base 

 well distinguished from the front ; apex of head blunt, produced 

 below the eye for less than length of the eye. Eyes large, promi- 

 nent, viewed from the side ovate, reaching below middle of side 

 of head. Antennae inserted near lower angle of eye, short, stout ; 

 basal joint not longer than head viewed from above, second 

 scarcely thinner at base than first. Pronotum tran.sverse, smooth, 

 anterior margin about half the length of the posterior, sides 

 ecarinate, nearly straight, anterior angles broadly rounded. Cal- 

 losities large, little elevated. Basal lobe of scutellum covered. 

 Elytra broad, costal margin considerably arcuated in the female, 

 nearly parallel in the male. Rostrum reaching onto base of 

 venter; oviduct of the female long, beginning before middle of 

 venter. Wing-cell without a hamus. Legs thick, irregularly 

 dotted, tibial spines stout, black. Tarsal claws small but longer 

 than in Macrotijlus; arolia free and connivent. 



Type of the genus Macrotylus angnlaris Uhler. 



The type species has much the aspect of a large Plagiognatlius, 

 but the absence of a hamus in the wing-cell and the free connivent 

 arolia places it in the Orthotglini, where there is no established 

 genus that will receive it. 



Pseudopsallus annularis (Uhler) 



This species and the next are broad forms, and have little in 

 common with the other genera of the Orthotylini, but they must 

 be placed in that tribe. Angularis is a slaty-brown species with 

 the claval suture, costa, the two principal nervures of the corium, 

 and the membranal nervures whitish, sometimes tinged with 

 yellow on the costa. The region of the callosities is black varied 

 with white, and the head is white, with the oblique impressions
