NORTH AMERICAN COLEOPTERA. 87 



process ]irolonged and acute ; legs ferruginous, fourth basal joint narrow and not 

 lobed beneath, the claws very slightly broader at base. Length .12 - .24 inch ; 

 3- 6 mm. 



In this species the apical and basal margins of the thorax are often 

 pale, and the extent of red at the base of the thorax varies from a 

 narrow space until it covers very nearly the basal half. The under 

 side of the body also varies in color fr(jm ])iceous to pale brown. 



This species is especially noteworthy from the abbreviation of the 

 outer carina of the juxta-sutural sulcus showing a tendency toward 

 Adelothyreus, which is further illustrated by the wide coxal plates 

 and the narrow fourth tarsal joint. 



By some inexplicable error Bonvouloir has described this species 

 as new, under the name meticulosus. The descriptions by Say and 

 LeConte are so clear as to the color, and this in connection with the 

 types in LeConte's cabinet leaves no doubt as to the species they both 

 had in view. 



Widely distributed over the United States from Canada southward, 

 and Bonvouloir reports it from Cordova, Mexico. 



ENTOMOPHTHAI.MITS Bonv. 



Antennae slender, nearly as long as the entire body, the second 

 and third joints very small, together shorter than the fourth. 



The other characters are as in Microrhagvis. The emargination of 

 the eye, from which Bonvouloir derives the generic name, is variable 

 in extent and does not form a character separating the two genera as 

 traces of a similar structure are observed in M. impressicollis. 



In our species the third antennal joint is smaller than the second, 

 while in his description Bonvouloir, by a lapsus ea/ttmrjcompares the 

 third joint with the fourth. 



There is but one species known in (jur fauna. 



E. riifioIu»<» Lee. — Form moderately elongate, slightly narrower behind, 

 ferruginous, moderately shining, sparsely clothed with very short fulvous pubes-

 coarsely not densely punctate . eyes feebly emarginate in front ; clyi^eus at base
