HEMIPTERA. VAN DUZEE. 3 
Wright of San Diego, who has turned over to me many interesting 
| Hemiptera and has given me valuable information respecting col- 
lecting grounds, and to Mr. J. L. Rose of Alpine, who has very 
kindly opened his Alpine home to me, where much of my back- 
country collecting has been done and which has proven an excel- 
lent place for Hemiptera work. 
This paper enumerates 392 species or distinct varieties, of 
| which 52 are new, and four new genera are characterized: Pycno- 
coris, Platycivius, Oeclidius and Rhynchopteryx. 
HETEROPTERA 
Family SCUTELLERIDAE 
Sphyrocoris punctellus Stal. Mussey’s, April, one example. 
Homoemus parvulus Germ. San Diego and Alpine; April. 
3. Homoemus proteus Stal. Mussey’s, August. 
4. Homoemus variegatus n. sp. 
Allied to proteus but much smaller; having much the aspect of 
Symphylus albomaculatus Dist., Length 4-5 mm. 
Female: Head shorter and broader anteriorly than in proteus; 
black or bronze black, closely punctured and covered with mottled 
pale pubescence. Antenne black, the incisures only pale; second 
and third joints subequal, fifth slightly longer than the fourth. ~ 
Pronotum proportionately shorter and broader than in proteus, 
the humeral angles a little more produced and the sides more obli- 
que, coarsely and irregularly punctured; color greyish tinged an- 
teriorly with ferruginous, the surface on either side covered with 
matted pale hairs; disk marked with irregular oblique blackish 
rays, the most pronounced of which forms an imperfect M across 
the middle of the disk and includes an abbreviated white medium 
longitudinal line; on the anterior margin before this dark mark is 
a pair of roundish black spots. Anterior half of the narrowly 
rounded lateral margins white, posterior half black. Scutellum 
shorter and broader than in proteus, grey, distinctly punctured with 
black and varied with blackish arcs; on either side of the base is a 
white arcuate line ending in a marginal spot of the same color 
and between which is a vague paler area. These pale marks are 
really formed by a whitish transverse band across the middle 
partially interrupted by a transverse brown cloud and two oblique 
blackish rays; posterior one half largely blackish marked with a 
triangular whitish apical spot and an obscurely triangular cloud 
either side. Elytra as in proteus, grey and punctured, the costa 
dotted with black posteriorly and the surface under the scutellum 
black. Beneath pale along the middle line with a blackish area on 
either side of the disk, the submargins being ferruginous or castan- 
eous. Middle of the venter with but few black punctures and 
clothed with a minute pale pubescence. Femora piceous black, pale 
at base and tip, with a rufous spot beneath; tibiz and tarsi castan- 
eous, the former piceous within, the latter black at apex. Osteolar 
canal less curved than in proteus; margins of the connexivum var- 
hoa
