Coleopterological Notices, V. 325 



median line finely and feebly impressed througliont. Elytra transverse, one- 

 third wider but not at all longer than the prothorax ; sides feebly arcuate ; 

 humeri broadly rounded and exposed ; disk broadly, feebly impressed at base. 

 Abdomen at base much narrower than the elytra and as wide as the prothorax ; 

 sides subparallel, broadly arcuate ; border thin and deep ; first three segments 

 finely, deeply impressed ; fifth shorter than the fourth ; under surface sparsely, 

 coarsely pubescent, finely punctate. Legs moderate ; posterior tarsi long but 

 much shorter than the tibiae, the basal joint somewhat thicker than usual and 

 very long, nearly as long as the next three. Length 3.6 mm. ; width 1.0 mm. 



Canada (Grimsby); Ohio. 



The distinguishing character of this species is the very wide 

 truncate sternal piece between the cox», much exceeding in width 

 that of any other known to me. The degree of separation of the 

 middle coxte bears no relation whatever to the width of the body, 

 for, in sonomae, which is a very much stouter species, the cox^ are 

 unusually narrowly separated. 



M. obliqiia n. sp. — Stout, subparallel, polished, black, the antennte red- 

 brown, paler toward base ; elytra pale rufous, clouded with blackish in a 

 basal subtriangular area and also broadly toward the external apical angles ; 

 apices of all the tergites and the legs throughout pale flavate ; head distinctly 

 but extremely remotely, the pronotum strongly, rather coarsely and decidedly 

 sparsely, punctate ; elytra rather coarsely, roughly but not densely so, the 

 punctures becoming however very dense toward the scutellum ; abdomen 

 finely, sparsely punctate throughout, with the pubescence long and fine, 

 coarser and more evident beneath ; pubescence anteriorly coarse and some- 

 what long but sparse, closer and more evident on the elytra. Head as long 

 as wide, three-fourths as wide as the prothorax, the eyes moderate, at their 

 own length from the base; tempera feebly convergent to the base; antennae 

 longer than the head and prothorax, the basal joint slightly thick, not as 

 long as the next two, third elongate, one-half longer than the second, not as 

 long as the next two, fourth quadrate, four to ten very evenly and moderately 

 increasing in width, the tenth rather shorter than the ninth, one-half wider 

 than long, eleventh thick, obtusely ogival, as long as the preceding two. 

 Prothorax fully two-fifths wider than long, widest at apical third, where the 

 sides are rather strongly rounded and convergent to the apex, somewhat 

 strongly convergent and nearly straight in basal half; base and apex sub- 

 equal, the former strongly, the latter feebly arcuate ; basal angles very obtuse 

 but evident, not distinctly blunt ; disk with a smooth, impuuctate but unim- 

 pressed median line and a small deep impression in the middle before the 

 base. Elytra one-half wider than long, two-fifths wider but only slightly 

 longer than the prothorax ; sides feebly divergent and slightly arcuate from 

 base to apex ; humeri obliquely, strongly rounded to the prothorax, not be- 

 coming transverse ; disk scarcely at all impressed. Abdomen broad, as wide as 

 the elytra ; sides parallel and just visibly arcuate ; border thick and not -vtiry
