237. Dictyobia atra n. sp. 
Size and form of permutata; deep black with a few pale marks 
on the carine and sutures, the elytra areolate with whitish-hyaline. 
Length 4-5 mm. 
Closely allied to permutata and presenting no really good 
structural characters. It may, however, be readily distinguished 
by its velvety black color, especially on the elytra, becoming some- 
what fuscous on the head, pronotum and scutellum with the carine 
slenderly and interruptedly edged with pale; disk of the front on 
either side and the clypeus brownish and there is a row of pale 
points near the lateral carine of the front, sometimes obscure; 
meso- and metasternum whitish. Pleural pieces more or less edged 
with pale; tip of the coxe, knees and tarsi in part also pale. Ab- 
domen black, the genital pieces and adjoining segments edged with 
pale; extreme tip of the mesosternum conspicuously pale. Elytra 
closely reticulated, the pale vittze obscured by black veinlets; none 
of the pale areoles materially larger as they are in permutata. 
These pale areoles form a diagonal vitta from the middle of the 
clavus to the costa behind the middle; this vitta is expanded on 
the costa and constricted or almost broken at the middle where it 
sends a branch consisting of two areoles toward the inner apical 
angle. There is a pale spot consisting of from four to five areoles 
on the costal margin almost midway between the end of the vitta 
and the base. The costz and apical margins have a row of white 
marks which become more regular and oval around the apex, and 
within this row at apex are two or three larger white areoles. All 
these markings consist of small whitish-hyaline aeroles separated 
by the black veinlets. 
Described from numerous examples taken on the chaparral 
from May to July, particularly at Alpine. This may be but a color 
variety of permutata but it is as distinct as are the several species of 
Dictyssa. 
238. Danepteryx manca Uhler. Abundant everywhere on Adenos- 
toma and Artemesia. It comes to maturity about April 1st 
but specimens may occasionally be found throughout the 
autumn and winter. This species varies from a fulvous 
brown to dark fuscous and sometimes a dorsal stripe and the 
elvtra are whitish or grey. 
239. Acanalonia mollicula n. sp. 
Form of clypeata nearly but with the elytra more narrowed 
toward their apex. Pale green or brownish with the sutural and 
apical margins slenderly brown. Length 5-6 mm. 
Vertex as in clypeata, distinctly subangularly produced, a very 
little longer on the middle than next the eye, slightly depressed on 
the disk, the anterior edge rounded. Front prominent basally, 
transversely convex, broader than its greatest length, deeply, an- 
gularly excavated for one half its length to receive the base of the 
clypeus. Pronotum scarcely as long as the vertex and like that 
obsoletely carinate. Mesonotum with the lateral caring feeble but 
descernable. Elytra nearly half as wide as long, costa strongly
