rated by nearly three times their width ; antennae rather slender, bnt slightly 

 more than one-third as long as the body, joints moderately obconical, about 

 three-fourths longer than wide, the third and fourth equal in length. Protho- 

 rax rather large, two-thirds wider than long, the apex subtruncate, nearly 

 as wide as the base, the latter transverse, the sinuations broad and distinct ; 

 sides somewhat strongly arcuate, the apical angles broadly rounded, basal 

 slightly obtuse but not rounded ; disk a little wider before the middle than at 

 base, broadly, feebly but distinctly impressed throughout along the middle, 

 finely, but strongly, rather sparsely punctate, the basal fovese large and feebly 

 impressed. Elytra about twice as long as wide, not quite four times as long 

 as the prothorax, and, in the middle, very slightly wider than the latter, 

 rather obtusely parabolic at apex ; sides parallel and feebly arcuate, the two 

 bases equal, humeri not exposed ; disk with feebly impressed lines, more 

 distinct toward the suture, the lines minutely, feebly punctate, the intervals 

 finely, confusedly, rather sparsely punctate, the punctures rather larger and 

 more distinct than those of the striae. Abdomen sparsely, extremely minutely 

 and scarcely perceptibly punctate. Legs slender, the basal joint of the hind 

 tarsi about as long as the remainder. Length 7.0 mm. ; width 2.5 mm.

The sex of the unique type is not apparent and cannot be deter- 

 mined without dissection. This species is not closely allied to any 

 other and may be readily distinguished by the characters given in 

 the table. 



M. procera n. sp. — Elongate, subdepressed, shining, piceous-black 

 throughout, the tarsi slightly paler ; pubescence fine, short, dark, moderately 

 dense, not conspicuous. Head small, feebly convex, more or less finely and 

 sparsely punctate ; eyes moderate, rather convex, separated by a little less 

 than twice their width ; antennae very slender, filiform, nearly one-half as 

 long as the body, third joint fully three times as long as the second and dis- 

 tinctly longer than the fourth. Prothorax small, but slightly wider, than the 

 head, about one-half wider than long ; apex subtruncate, three-fourths as wide 

 as the base, the latter broadly, just visibly arcuate ; sides almost straight and 

 parallel in basal two-thirds, then broadly rounded to the apex ; basal angles 

 right, not rounded ; disk feebly convex, more or less finely and sparsely, but 

 very distinctly punctate, broadly, feebly impressed in the middle near the 

 basal margin, broadly explanate toward the basal angles, the basal foveae 

 nearly obsolete. Elytra between five and six times as long as the prothorax, 

 and, behind the middle, about twice as wide ; sides parallel, feebly arcuate 

 behind ; apex rather abruptly ogival ; humeri broadly rounded and widely 

 exposed ; disk finely, somewhat densely punctate, the fine, feebly impressed 

 lines distinct, but without definite punctured series, the punctures generally 

 however with a closely subseriate arrangement. Under surface polished, very 

 finely, sparsely punctate. Legs long, rather slender ; posterior tarsi equal in 

 length to the tibiae, the basal joint scarcely longer than the next two com- 

 bined. Length 5.5-6.0 mm. ; 1.8-2.0 mm.
