26 COLEOPTERA RHYNCHOPHORA. 



hairs of the under surface are entirely simple, even upon the 

 episterna, which are so often clothed with radio-pectinate 

 hairs in this genus. 



M. lliorio n. sp. — Rather strongly cuneiform black throughout, 

 lustre dull, above glabrous, beneath with sparse fine hairs, a few of which 

 become radio-pectinate on the sternal side pieces. Beak (c?) evenly 

 moderately arcuate, three-fourths as long as the head and prothorax, 

 evenly rather closely punctate, a short smooth line above the insertion 

 of the antennae, Antennae inserted at basal three-sevenths, scape 

 reaching the eye, first and second funicular joints subequal, each a 

 little less than twice as long as wide, the second about as long as the 

 third and fourth together. Head moderately punctate, a small fovea 

 or impressed puncture between the eyes, the latter rather flat and 

 separated by about three-fourths the width of the beak. Prothorax 

 conical, as wide at base as long, sides nearly straight, suddenly con- 

 stricted at apex, surface densely rather coarsely punctate, without 

 trace of median impunctate line. Elytra gradually widening to apical 

 third, where they are one-half wider than the greatest thoracic width ; 

 strial punctures rather fine, striae not impressed, intervals wide, fiat, 

 interstitial punctures fine, forming a single line on the eighth inter- 

 space, more or less irregular or double on the others. Body beneath 

 densely punctured. Length 6 mm. 



Santa Rita Mountains, Arizona (Snow); Chiricahua Moun- 

 tains, Arizona (Hubbard and Schwarz); Magdalena Moun- 

 tains, New Mexico (Snow). 



The type is a c? from the first named locality, and has the 

 abdomen concave at base, the median portions of the last 

 three or four segments clothed with numerous short erect 

 hairs. 



It differs from aineifortnis by its color, dull lustre, finer 

 less impressed elytral series and wider intervals. 



M. hispoides Lee. 



This species is quite out of place in the Check List, doubt- 

 less because Le Conte in his description made no compari- 

 sons with older forms ; the simple femora and claws, how- 

 ever, at once declare its position. It is very widely diffused, 

 occurring from. Maine to British Columbia (type locality) 

 and extending down into New Mexico and California. Some 

 variation exists as might be expected in so wide a range, 

 the Californian specimens showing a tendency toward a
