apparently on the same level as the presternum. The fourth joint 

 of the maxillary palpi is in the form of a right-angled triangle, 

 thick, convex, twice as wide, and more than twice as long as the 

 third. The abdomen is a little more densely and finely punctured 

 toward apex. 



M. longipeiinis n. sp. — Oblong-elongate, rather depressed, parallel, 

 polished, rather pale piceous-brown throughout; legs more flavate ; pubes- 

 cence fine, short, not dense, pale but inconspicuous. Head rather large, 

 transversely flat between the eyes, which are very large and prominent, sepa- 

 rated by about their own width; punctures rather dense, somewhat coarse 

 and confused; antennae nearly two-fifths as long as the body, moderately 

 robust, feebly, gradually attenuate, third joint long, distinctly longer than 

 the fourth, joints fi^e to eleven equal in length and much shorter than the 

 fourth. Prothorax scarcely one-half wider than the head, three-fourths wider 

 than long ; apex trmicate, two-thirds as wide as the base, the latter trans- 

 verse, the lateral sinuations broad but distinct ; sides broadly rounded and 

 convergent anteriorly, parallel and nearly straight in basal half; basal angles 

 right, very narrowly rounded ; disk rather abruptly, narrowly explanate at 

 the sides anteriorly, gradually deplanate toward the basal angles, broadly, 

 feebly impressed along the middle, not very densely, rather coarsely and 

 roughly punctate ; basal foveas broadly, feebly impressed and indefinite. 

 Elytra nearly five times as long as the prothorax, and, throughout, about one- 

 fourth wider, parallel, the sides straight ; humeri rather abruptly rounded 

 and slightly exposed ; apex somewhat abruptly obtusely rounded ; disk finely, 

 rather sparsely punctate, the impressed lines rather distinct throughout the 

 width, the punctures having a generally closely seriate arrangement, but 

 without any definite series of larger punctures. Under surface very sparsely, 

 finely punctate. L*gs normal, the basal joint of the hind tarsi nearly as long 

 as the remainder. Length 6.8 mm. ; width 2.2 mm. 



California (San Bernardino). 



The anterior coxse are large but not very prominent, and are 

 separated throughout their length and depth by a thin prosternal 

 lamina, the exposed surface of which is strongly, longitudinally con- 

 vex. The species is not closely allied to any other before me, and 

 may be known by its parallel depressed form, large eyes and pecu- 

 liar antennal structure. 



M. pacifiea n. sp. — Oblong, rather feebly convex, subparallel, piceous- 

 black, the under surface but slightly paler ; legs and antennas dark brown ; 

 lustre shining, the anterior parts just visibly alutaceous ; pubescence very 

 short, sparse, recumbent and inconspicuous. Head rather convex, finely, 

 rather sparsely punctate, the epistoma abruptly deplanate ; eyes small, sepa-
