apparently on tlio same level as the prosternuni. The fourth joint 

 of the niaxillar}' palpi is in the form of a right-angled triangle, 

 thick, conv(;x, twiee as wide, and more than twice as long as the 

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

 toward apex. 



9t, lon$;il>eilIlis n. sp. — Oblong-cloiisatc, ratlicr depressed, par.allel, 

 polished, rather pale piceons-Lrown throughout; legs more Havate ; pubes- 

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

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

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

 and confused; anteniuc nearly two-lifths as long as the body, moderately 

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

 the fourth, joints five to eleven equal in length and nmch shorter than the 

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

 than long; apex truncate, 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, 

 ft!ebly impressed along the middle, not very densely, rather coarsely and 

 roughly- punctate ; basal fove<e broadly, feebly impi'essed 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 fintdy, 

 rather sparsely jiunctate, 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 (j.8 mm. ; width 2.2 mm. 



California (San Bernardino). 



The anterior coxa? are large hut not very prominent, and are 

 separated throughout their length and depth by a thin prosternal 

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

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

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

 liar antennal structure. 



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

 blaek, the under surface but slightly paler ; legs and antennae dark brown ; 

 lustre shining, the anterior pai'ts just visibly alutaceous; pubescence very 

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

 rather sparsely punctate, the epistoma abrui)tly deplanate ; eyes small, sepa-
