Tlie series before me consists of two males and ten females 
from Berkeley (type cf), Belmont, IMonterey, Point Reyes, 
Pacific Grove and Lagunitas. 
This species is closely related to laticeps and doubtless so 
stands in collections. To the characters given in the table for 
their distinction there may be added — antennae subserrate in the 
male of laticeps, scarcely at all so in franciscanus; legs largely 
pale in male laticeps, almost entirely dark in franciscanus; the 
pale margin of the prothorax, though narrow, is as a rule wider 
in laticeps and is entire, while in franciscanus it completely or 
virtually disappears for a greater or less distance along the front 
margin, and in several examples exists only along the extreme 
edge about the basal angles. In the second male of my series 
(Monterey) the pale color at the tips of the elytra is reduced al- 
most to the vanishing point, while in a IMonterey female in Dr. 
Fenyes’ collection and in my single male of laticeps it is entirely 
lost. 
Microlipus laticeps LeConte, Proc. Acad. Nat. Sci. Phila., 1852, p. 168. 
This species, the type of the genus Microlipus and the first to 
be made known, was described in 1852 from San Diego specimens. 
LeConte’s description is not now accessible to me, but Horn in 
his Synopsis of the iVIalachiidae in 1872 remarks that all known 
specimens are males. This, however, is not true, the specimen 
on the name label — evidently one of the original series — being 
a female. I have almost exactly similar females from San 
Diego, and with them associate without hesitation a male from 
Long Beach, about ninety miles farther up the coast. This 
species, I suspect, is confined to the Southern California Coast 
region, being replaced by the closely allied but apparently dis- 
tinct franciscanus in the IMiddle Coast region. For differences 
observed between these two, in addition to those of the table, see 
remarks under franciscanus. 
Microlipus aequalis new species 
Aeneo-piceous, prothorax rufo-testaceous with broad median piceous stripe, 
which does not quite reach either the basal or apical margins; legs largely 
pale in color, the apical half of the femora piceous, the tibiae dusky; mouth and 
tips of elytra pale. Antennae fully two-thirds as long as the body in the male, 
not appreciably serrate, rather less than half as long as the bod}' in the female, 
piceous with the underside of basal four joints pale in both sexes. Head not 
appreciably wider than the prothorax in the male, the latter wider than long
