Nov., 1916] Neiv Species of Nearctic Tingidce 11 



Corythucha immaculata spec, no v. 



Antennas beset with a few long bristly hairs; first segment slightly 

 more than twice the length of the second, moderateh' swollen; second 

 segment short, less swollen than the first; fourth segment swollen 

 toward the apex. Rostrum reaching between the posterior coxae. 

 Membranous pronotal margins broad, kidney-shaped, bullate about the 

 middle, slightly turned up at the posterior margins, entire outer margins 

 anned with rather small, closely set spines. Hood closely reticulated, 

 abruptly constricted about the middle ; anterior portion long and nar- 

 row; posterior portion subglobose. Pronotum more or less indistinctly 

 reticulated; sides of posterior triangular process rather strongly raised 

 anteriorly, with five or six distinct areolae. Median carina foliaceous, 

 with two nearly complete irregular series of unequal areolae. Wings a 

 little longer than the abdomen. Elytra quite closely reticulated, outer 

 margin slightly sinuate; costal area rather coarsely and unevenly 

 reticulated, with three complete and a partial series of areolae; sub- 

 costal, discoidal, and sutural areas (except row of large cells on inner 

 margin) closely reticulated. Length, 4.1 mm.; width, 2.15 mm. 



Color: Body beneath black. Legs and antennas testaceous. Ner- 

 vures of hood, membranous pronotal margins, posterior triangular 

 process of pronotum, and elytra yellowish. Areolae translucent. 



Described from two specimens, taken at Alameda, Cali- 

 fornia, by Mr. Albert Koebele. We have one specimen from 

 Santa Cruz Mountains, California, that has a few nervures 

 slightly tinged with testaceous. 



Corythucha obliqua spec. nov. 



Antennae beset with a few long, stiff hairs ; first segment moderately 

 swollen, about twice the length of the second; second segment less 

 swollen, shortest; third segment very long, cylindrical; fourth segment 

 considerably swollen towards the apex. Rostral groove rather broad; 

 rostrum reaching the intermediate coxse. Pronotum coarsely and 

 regularly punctured; membranous margins broad, kidney-shaped, 

 quite closely reticulated, strongly bullate about the middle, slightly 

 reflected behind, the dorsal surface armed with a few erect spines; 

 posterior, triangular portion reticulated at the apex, the sides raised 

 anteriorly, with five or six distinct areola; median carina considerably 

 raised, with one complete row and two divided areolae about the middle 

 forming double cells. Hood moderately raised, rather closely retic- 

 ulated, armed with a few short spines on the sides, quite abruptly con- 

 stricted about the middle, globose behind. Wings a little longer than 

 the abdomen. Elytra broadly rounded at the apex, outer margin 

 slightly sinuate; costal area with three complete series and a partial 

 row of areolae near the base. Length, 3.45 mm.; width, 1.44 mm. 



Color: Antennae yellowish. Legs dusky-yellow; tarsi somewhat 

 embrowned. Body beneath black. Hood dark-fuscous, except a few
