412 AMERICAN PACHYBRACHYS (cOLEOPTERA) 



eyes, less slender antennae, still more confused elytral punctua- 

 tion, broader front tarsi, normal pygidium and smaller size. 



94. Pachybrachys sanrita Bowditch 



Of more than average size, prothorax broadly suffused with 

 reddish brown, elytral markings black or dark brown, predomi- 

 nant, and usually confluent in such fashion as to leave the apex, 

 two lateral transverse fasciae (often more or less broken), the 

 shield, some short basal lines, and scattered small spots near the 

 suture, yellow. Ej^es (cf) evidently though not greatly more 

 distant than the vertical width of their upper lobes; ocular lines 

 wanting; front claws of male not apprecialjly enlarged. Ave. 

 length 4 mm. Arizona. 



//e«rf barely as wide as the thoracic apex, unevenly rather finely punctured, 

 the darker areas diffuse, reddish brown, sometimes almost obsolete. Eyes 

 separated in the male by al^out twice and in the female by about three times 

 the length of the basal antcnnal joint. Antennae yellow, outer joints blackish, 

 fully three-fourths as long as the body in the male, the tenth joint fully three 

 times as long as wide; scarcely more than half as long as the body in the female, 

 the tenth joint less than three times as long as wide. 



Prothorax widest at about basal fourth, sides nearly straight and distinctly 

 convergent anteriorly, rounded in a little at base, with a slight sinuation before 

 the angles; punctuation somewhat uneven, not very close, side margins nar- 

 rowly smooth; M broadly suffused, leaving the side margins and front angles 

 and two more or less obvious basal spots and a narrow median anterior line, 

 yellow. 



Elytral striae cjuite irregular, the second, third and eighth best defined, the 

 discal ones slightly, the eighth distinctly impressed; second and third inter- 

 spaces wide behind the middle; the shield distinct, yellow; discal series of 

 punctures often showing a tendency to become irregularly double; submarginal 

 stria strongly sinuous, marginal interspace without punctures; outer spots con- 

 nected with the corresponding inner ones, the latter completely confluent 

 longitudinally, leaving only the suture and some small adjacent spots, the 

 basal margin, two or three narrow basal spots, the shield, two larger transverse 

 lateral spots, and the apex, yellow. 



Pygidium brown with apical yellow sjjots. Body bcncnlh lirown, last 

 ventral partly yellow. Legs rufo-testaceous, the tips of the middle and hind 

 femora pale yellow. 



Length 3.7 to 4.2.5 mm.; width 2 to 2.2.5 mm.

 tains (Schaeffer), (Leng), (Beyer); Palmerlee, Cochise Co., July (Schaeffer),
