RUTELIN^; 23 



deep, close-set and conspicuous. Male with the larger anterior claw 

 rather slender, abruptly bent basally as usual, cleft in nearly apical 

 third, the upper ramus much more slender than the lower but almost 

 as long; in the female not differing so much as usual, the lobes more 

 diverging, the upper relatively a little thicker. Length (cf 9 ) 

 10.5-11.7 mm.; width 5.8-7.0 mm. Southern Texas. Seven male 



examples and one female luteipennis Lee. 



Color bright testaceo-rufous above and beneath, the elytra paler and 

 more flavate; anterior parts never blackish, the tarsi more or less 

 blackish, rather shining ; head (cf ) almost as large as in the preceding, 

 with the large convex eyes separated by fully twice their widths, or 

 (9) with the eyes not quite so large and notably less prominent; 

 front feebly impressed, with the usual close punctato-rugulose 

 sculpture somewhat feeble, also pervading the clypeus, which is 

 about twice as wide as long, transversely arcuate at tip, with widely 

 rounded angles, the sides often continuously rounded, the apex widely 

 and strongly reflexed; antennae as in luteipennis, the club rather less 

 elongate but longer than the stem in the male; prothorax nearly sim- 

 ilar but with the rather fine sparse punctures feebler; elytra as in the 

 preceding, with the fourth interval generally narrowly and confusedly 

 punctured along the middle, but in one, from Vowell's Mill, broader 

 and with the area of confused punctures much wider; pygidium 

 convex, always testaceous, with the arcuate punctures shallower 

 and sparser than in luteipennis; tarsal claws nearly similar. Length 

 (cf 9 ) 9.0-11.0 mm.; width 5.2-6.3 mm. North Carolina (Southern 

 Pines regarded as the typical locality, as the type was sent by 

 Zimmermann) to Louisiana (Vowell's Mill). [A. dichroa Mels.] 

 Five males and one female, the latter, from Vowell's Mill, smaller 

 and notably more slender than the male and represented above by 



the smaller dimensions flavipennis Burm. 



A Similar but on the whole rather larger, notably stouter and with 

 stronger sculpture, as seen very well in extended series; head 

 similar but with the eyes (cf ) not so prominent, being separated 

 by distinctly more than twice their own width and with larger 

 and broader clypeus, or ( 9 ) separated by nearly three times their 

 width; prothorax similar but generally with the indefinite im- 

 pression on the median line at basal third more evident; elytra 

 nearly similar; disk rarely with one or two short longitudinal 

 piceous lines before the middle not observable in any of my 

 examples of flavipennis; pygidial sculpture rather closer and more 

 pronounced as a rule, the claws similar. Female relatively not 

 so slender as in flavipennis, similarly rare in individuals. Length 

 (cf 9 ) 9.5-11.5 mm.; width 6.0-6.8 mm. Kansas (McPherson 

 and Lucas). Abundant. Fourteen males and two females. 



modulata n. subsp. 



B Nearly similar but rather more elongate; head (cf ) nearly as in 

 flavipennis, the concave clypeus with the sides arcuate from the 

 base through the apex and broadly, strongly reflexed, the eyes 

 separated by but slightly less than twice their width; prothorax 

 similar but with the sides more rounded, becoming relatively
