promiueut, obtuse, scarcely I'ounded, and in the form of wide cusps; base 

 broadly and rather strongly arcuate, very feebly siuiiate near the bas;d 

 angles, about equal in width to the apex which is transversely truncate; 

 disk rather strongly convex, especially anteriorly and laterallj', even, very 

 finely, rather sparselj' and evenly punctate. Elytra at base about one-fifth 

 wider than the pronotum; sides very feebly divergent and almost straight; 

 disk as wide as long, depressed, even, nearly one-third longer than the pro- 

 notum, rather coarsely, moderately densely and deeply punctMte; punctures 

 somewhat asperate. Abdomen much narrower than the elytra; sides sub- 

 parallel and feebly arcuat^, rather finely- and closely punctate; punctures 

 becoming much more sparse toward the apex; border nairow and rather 

 deep. Legs rather long very slender; first joint of the posterior tarsi slightly 

 shorter than the next three together. Length 2.6-2.9 mm. 



California (Hoopa Yal., Humboldt Co., 8). 



This species occurs Avitli the preceding but is very much 

 less abundant; I have also received one specimen collected 

 by Mr. C. Fnchs near San Mateo. It is distinguished at 

 once by its very dark color, more slender form, by the much 

 finer punctuation, especially of the head and pronotum, 

 the more slender antennoe, and by the form of the pronotum.

M. californica ^- sp. — Moderately robust; sides parallel; bodj' intense 

 black throughout except the last two segments of the abdomen which are 

 dark fus.ous above and beneath, the base of the penultimate being black; 

 antenn;e black, scarcely paler toward ba<e; legs black, tarsi very slightly 

 paler, rufo-piceous; pubescence verj' sparse, erect and fine on the anterior 

 portions, absent on the abdomen above, except along the apices of the 

 segments which are setigerous; much denser and rather fine beneath, with 

 numerous long, erect, black bristles, especially toward the apex; anterior por- 

 tion of the body finely but strongly grauulose, alutaceous; abdomen polished. 

 Head slightly longer than wide; occiput and front feebly and evenly convex, 

 finelj', feebly and very sparsely punctate; sides behind the eyes moderately 

 convergent and arcuate; antennas one-half longer than the head, rather 

 robust, strongly compressed, four basal joints glabrous although sparsely 

 setigerous, remainder covered densely with a short fulvous pubescence with 

 manj' long erect setas at the apices; basal joint three times as long as wide, 

 distinctly shorter than the next two together, as long as the third and fourth, 

 second much shorter than the third, fourth smallest, as wide as long. Pro- 

 thorax widest at one-third its length from the apex where it is one-fourth 

 ■wider than long; sides strongly and evenly arcuate, slightly convergent
