374 AMERICAN PACHYBRACHYS (cOLEOPTERA) 



mm. long, very similar in nearly every respect, but the eyes seem 

 slightly more distant and there is no trace of the short sparse 

 pubescence seen in typical fortis, though this I suspect may easily 

 be lost by abrasion. 

 58. Pachybrachys femoratus Olivier 



Small to medium in size, females quite robust, blackish and 

 dull yellow, mottled, the darker color usually in excess on the 

 prothorax, and often on the elytra; punctuation rather dense, 

 broadly confused on the elytral disk; no ocular lines; front claws of 

 male distinctly enlarged. Ave. length 2.75 mm. Atlantic Coast 

 and Gulf States. 



Head not wider than the thoracic apex, blackish markings more or less 

 broad and closely punctate, yellow areas sparsely so. Eyes separated by the 

 length of the basal two joints of the antennae in the male and by twice the 

 length of the basal joint in the female. Antennae one-half ( 9 ) or two-thirds 

 (cT) the length of the body, dull yellow basally, tenth joint scarcely more than 

 twice as long as wide. 



Prothorax distinctly narrowed in front, widest and rather strongly rounded 

 before the base, especially in the male, sides a little incurved before the hind 

 angles; markings broad and diffuse, pale areas usually small and a little con- 

 vex, the punctuation dense in the dark spaces; side margins not smooth or only 

 partially and very narrowly so. 



Elytra broadly confusedly punctate baso-medially, elsewhere with irregular 

 unimpressed series of punctures, becoming lightly impressed striae only at the 

 sides and on the rear convexity; shield small and in some examples scarcely 

 defined; marginal interspace narrowed apically, not wider than the adjacent 

 one, more or less punctate (rarely almost impunctate) in the male, in the 

 female punctate almost or quite tliroughout, the punctures of the interval 

 frequently confused with those of the stria basally; maculation variable, the 

 standard spots — especially the inner ones — poorly defined. 



Pygidium black with two oblique apical spots, often confluent at their tijis, 

 and a small spot at the middle of each side margin, yellow; this latter con- 

 tiguous to a yellow spot at the side of the last abdominal segment, the abdomi- 

 nal spot sometimes produced along the apical margin of the segment. Legs 

 yellow, femora and tibiae with black or brown more or less diffuse median 

 spots. 



Length 2.6 to 3 mm.; width 1.45 to 1.75 mm.
