females are not only generally larger and more robust than the males, a 
length of 11 mm. and a breadth of 4.5 mm., as against a length of 9.5 mm. 
and a breadth of 3.5 mm. for the males, but that’ they have proportionally 
a more robust prothorax, with the sides more rounded, and more gen- 
erally piceo-testaceous in color as contrasted with the usual uniform black 
of the males. In this last regard they agree with the only two other fe- 
males known, the type female in the Horn collection and the female in the 
LeConte collection. 
Dichelonycha decolorata Fall—vThis species has been found to be one of 
the characteristic insects of that most! interesting faunal region situated | 
about Monterey, Cal. They are very abundant during May, flying about 
the Monterey pines. 
Dichelonycha vicina Fall—I find this species in the coast belt of Cali- 
fornia as well as in the Sierras. I have specimens from the following 
coastal countries: Santa Cruz, Marin, and Sonoma. It is generally found 
towards the last of May and first of June, about a month later than the 
last D. valida Lec., a species with which it is often confused, and the speci- 
mens are generally to be found about the Douglas firs, whereas the others 
favor the redwoods. 
Cremastochilus hirsutus n. sp.—Robust, castaneous, subopaque, clothed 
with yellowish pubescence, long on the elytra and median portion of pro- 
notum, elsewhere moderate in length. Head moderately closely punctured 
posteriorly, finely and sparsely punctured in front, occipital region trans- 
versely depressed, widest across eyes and rapidly narrowing behind them; 
clypeus viewed from above, rounded at sides and almost transverse in 
front, with a well-marked carina at middle which, however, does not reach 
the anterior margin but' projects forward free and horn-like, margin widely 
reflexed and forming an elevated semicircle as seen from in front, fim- 
briated at sides; submental plate transversely oval, pointed behind, the 
sides and posterior margin reflexed, the latter quite markedly. Thorax 
broad, almost as wide as the elytra, narrowed behind, sides arcuate in 
front, suddenly excavated posteriorly to the posterior angles, which are 
acute, of moderate length, and project directly backwards, anterior angles 
with a deep incision forming in front an auriculate lobe, anterior margin 
deeply semicircularly emarginate, disc trilobed, the median portion some- 
what depressed, with a longitudinal impression at middle, surface coarsely 
but shallowly punctured and somewhat subopaque, the lateral portions 
coarsely and deeply punctured outwardly and smooth toward inner bound- 
ing sulci and posterior angles. Elytra with disc flat, sides nearly vertical, 
discal region with irregular, shallow, elongate, and more or less confluent 
variolate fovez, surface more or less subopaque. Body beneath coarsely, 
sparsely punctured on thorax, finely punctured in transverse rows on 
abdomen, all markedly hairy as above. Legs not unusually dilated, ante- 
rior tibia with the upper tooth near the middle and the terminal long and
