NORTH AMERICAN MALACHIIDAE 
Antennae (cf) long and stout, moderately serrate, basal three joints pale be- 
neath. Pro thorax transversely, broadly oval, minutely, very sparsely punctu- 
late. Elytra (cf) but little widened behind, finely punctulate and with the 
usual vestiture. Body beneath pale red, the legs black, the trochanters and 
base of front and middle femora pale, tarsi and tips of tibiae brownish. 
Length, 3.25 mm. 
California: Havilah. A single male collected by G. R. Pilate. 
This species strongly resembles in color certain specimens of 
abdominalis, but is at once separable, by the tabular characters. 
It is also very similar in color to several species of Attains. 
MICROLIPUS LeConte 
The genus MicroUpus contains a few slender Malachius-\ike 
species of Coleoptera, which are, with a single exception, members 
of the extreme West Coast fauna. They are not overly abun- 
dant in collections and there are few references to them in the 
books. A critical examination of the material in my own cabinet 
and that of Dr. Fenyes reveals the presence of three apparently 
distinct forms allied to laticeps, and with the description of these 
it has been thought well to present a synoptic table, together with 
brief references to all the known species, followed by some ob- 
servations concerning the standing of the genus itself. 
Table of Species 
Elytra not appendiculate in the male, both sexes winged ; pronotum as viewed 
in profile not conspicuously reflexo-explanate posteriorly, and scarcely more 
so than in front. 
Antennae pectinate in the male prolixicomis 
Antennae not pectinate in the male. 
Prothorax smooth and shining, distinctly wider than long. . . .laevicollis 
Prothorax punctulate and more or less finely alutaceous, less shining. 
Antennae of male as long as the entire body, dorsal cloud of pronotum 
small or obsolescent productus 
Antennae of male much shorter, one-half to three-fourths the length 
of the body, pronotum with broad dorsal dark stripe or with the 
margins alone narrowly pale. 
Prothorax, at least in the male, as long as wide or very nearly so, 
pale margins narrow. 
Elytra distinctly inflated posteriorly in the female; head, including 
the eyes, scarcely wider in the male than the prothorax, pale side 
margins of the latter very narrow, sometimes merely vestigial.
