HEMIPTERA. VAN DUZEE. 41 
and meta-pleura infuscated on their disk. Abdomen black the 
extreme apex and larger lateral angles fulvous; carine pale; meso- 
margins slenderly pale. Legs soiled testaceous, the tarsal spines 
infuscated. Elytra faintly hyaline-smoky, the nervures fuscous, 
those at apex stronger, the transverse nervures more heavily infus- 
cated, with a larger smoky spot behind the stigma and another be- 
yond the apex of the clavus. Wings vitreous with fuscous veins. 
Last ventral segment of the male with a deep oblong sinus 
including most of the genitalia; pygofers slightly emarginate be- 
low, the stiles ligulate and approximate, at their apex extended lat- 
erally, and truncate, their apex considerably exceeded by the nar- 
row pygofers. 
Described from numerous examples swept from weeds, grasses 
and low bushes at East San Diego, La Mesa, Lemon Grove, Lake- 
side and Alpine in San Diego County, California, during April and 
May 1913. 
229. Dictyssa marginepunctata Melich. Of this nearly black spe- 
cies I have taken single examples at San Diego, Lakeside, 
Mussey’s and in the Cuyamacas, May to October. Taken on 
Adenostoma. 
230. Dictyssa obliquua Ball. May to August. Common. This and 
the following species are to be found on sage brush, Arte- 
mesia. 
231. Dictyssa mutata Melich. Common in May. 
232. Dictyssa fenestrata Ball. La Jolla, June 25th, 1913; three 
examples. 
233. Dictyssa transversa n. sp. 
Small, pale grey; Elytra hyaline, veined with brown and cross- 
ed by two brown vitte. Length 214 mm. 
Cinerous brown; front brown with whitish carinze boarded 
with darker. Vertex, pro- and mesonotum varied with darker and 
with the median carinze obscurely paler; abdomen dark brown. 
Elytra whitish hyaline, reticulated with brown nervures and cross- 
ed by two narrow transverse brown vitte; the anterior at about the 
middle and more or less interrupted, the posterior just beyond the 
tip of the clavus, entire but somewhat irregular. The front a little 
narrower than in mutata. 
Described from numerous specimens mostly taken on the slopes 
of Mt. Soledad at La Jolla, from September to November. Also 
taken at Alpine in March and October and at Torrey Pines in 
June. The closely reticulated hyaline elytra and the small size will 
distinguishe this species. Like most of its congeners it lives on 
Artemesia. 
234. Naethus fenestratus Melich. Mussey’s and Alpine, June to 
August. On oaks in the chaparral. 
235. Naethus nigronervosus Melich. June to October. Abundant 
on scrub oaks. 
236. Dictyobia permutata Uhler. Foster, May; one example.
