HEMIPTERA. VAN DUZEE. 26 
149. Platytylellus basivittis Stal. Occasional, April to July. I 
have taken some color varieties which probably are not dis- 
tinct from this species. 
150. Stenodema gracilis n. sp. 
Aspect of vicina but more slender with the antennx black or 
nearly so. Length 7-8 mm. 
_. Head a little more produced before the antenne than in 
vicina, the median sulcus distinct; Antenne longer, first joint thin- 
her and distinctly longer than in that species, as long as the pro- 
notum. Rostrum attaining the hind coxe, the first joint just 
reaching the base of the head. Pronotum narrower and more con- 
vex than in the allied species, coarsely punctured, the median 
Smooth line nearly obsolete; sides sharply carinate, narrowly folia- 
ceous. Basal lobe of the scutellum a little exposed, disk of poste- 
rior lobe obscurely transversely punctate or rugose. Elytra slen- 
der, parallel, punctured except on the broad costal area and cuneus. 
Legs shorter and more slender than in vicina. 
Color: Female, yellowish-testaceous. Antenne dark casta- 
neous or piceous black; a broad black vitta covers the sides of the 
ead including the base of the antennze and the eyes, crosses the 
pronotum and covers the basal angles of the scutellum. Elytra 
dusky brownish with the smooth costal margin and cuneus pale. 
Beneath and legs palé with indications of a longitudinal vitta across 
the pleural pieces and sides of the abdomen; tip of the rostrum and 
tarsi black; femora not dotted. The basal joint of the antennz is 
paler beneath and the middle line of the rostrum is dark. 
In the male the black vittae above and below are much extend- 
ed, covering most of the surface; above omitting a nearly parallel 
yellowish median vitta to the apex of the scutellum, and the ex- 
panded sides of the pronotum and elytra; the disk of the elytra is 
dark brown, more blackish on the scutellum. Antenne black; ros- 
trum as in the female; the femora a little darker. 
Described from numerous specimens of both sexes taken at 
San Diego, Lakeside and Mussey’s during April and May. From 
arberry in Canada I have received a pale example of what is prob- 
ably this same species, showing a wide range to the north. Al- 
though the base of the scutellum is narrowly exposed the base of 
€ pronotum is truncate and the species evidently belongs to 
Stenodema. 
151. Trigonotylus breviceps Jakw. This species which I believe 
I have rightly identified is common on a low fine grass 
growing in moist locations at most places where I have col- 
lected in this county. It is found throughout the year. 
152. Dicyphus californicus Stal. April and May. Common. 
158. Dieyphus vestitus Uhler. Occasional in the back country 
from April to June. I have taken few individuals of this 
species that are as dark as indicated by Dr. Uhler. 
154, Dicyphus minutus Uhler. April, a few only. 
155. Paraproba pendula n. sp. 
Allied to fasciata Dist. but evidently distinct. Whitish; head
