NORTH AMERICAN GEOTRUPINAE — ^HOWDEN 211 



lazarus lazarus, second and fourth intervals slightly wider than others, 

 and usually with a line of fine punctures. Humerus of elytron bearing 

 a small sharp tubercle at edge. Foremargin of eye canthus scarcely 

 produced forward at outer angle, slightly more sharply rounded than 

 in typical lazarus. The lamellae of the antennal club noticeably 

 longer than the eye (as in lazarus lazarus). Male with very pro- 

 nounced clj'^peal horn, almost twice as long as wide. Clypeal horn of 

 female small and thin, slightly bifid. Horn of vertex more pronounced, 

 noticeably bifid. Pronotal modifications of male identical to well 

 developed males of lazarus lazarus, females similar to females of 

 lazarus lazarus. 



No useful characteristics were noted in male genitalia or genital 

 capsule. 



Variation in size, color, or other noticeable characters is very slight. 

 Cartwright described this species as a variety of lazarus, but none of 

 the specimens known have been collected in areas with lazarus lazarus. 

 Specimens of alutaceus occur along the Gulf of Mexico, within the 

 range of suhtropicus. As it is very distinct from subtropicus it is my 

 opinion that it is a separate species. It is easily distinguished by its 

 dorsal alutaceus appearance. 



Most of the known specimens were collected at light and there is 

 no information available concerning either the adult or larval biology. 



Specimens examined: 14 males, 9 females.

Eucanthus greeni Robinson 



Eucanthus greeni Robinson, 1948, pp. 30-31. Type, male, New Mexico (Robin- 

 son). 



Some of the following discussion has been taken from Robinson's 

 original description and has been added to and rewritten merely for 

 the sake of uniformity. 



Length 8.3 to 11 mm., greatest width 4.9 to 6.8 mm. 



Color of dorsum shining reddish brown with eyes, tips of horn, 

 edge of eye canthus, anterior and posterior edges of pronotum, and 

 sutural intervals darker brown to black. Antennal club light reddish 

 brown in color. Ventral portions of thorax and abdomen the same or 

 slightly darker in color than dorsally. Tibia dark brown to black. 

 In male, coarse punctures of vertex absent, which is also usually true 

 in the female. Moderately coarse pronotal punctures are present on
