more converging apically, the medial impression at basal third 

 distinct but similarly shallow; elytra longer, similarly sculptured, 

 pale brownish-flavate, the type nubilate with brown in certain 

 discal areas before the middle and also about the humeri; pygidium 

 more shallowly and sparsely arcuato-punctulate than in either of 

 the preceding. Length (cf ) 11.2 mm.; width 6.0 mm. A single 

 example, received from a European dealer and marked "Cal." 

 but probably in error possibly from Arizona. 



amissa n. subsp. 



Color testaceous, the head, pronotum, suture, margin, sides of the elytra 

 basally and the legs reddish, shining, the form somewhat as in 

 binotata; head coarsely and densely punctate; clypeus transverse, 

 the apex subtruncate, the angles rounded and the margins moder- 

 ately reflexed, the suture distinct; prothorax shining, convex, sparsely 

 punctate, the sides slightly arcuate; hind angles rounded, the an- 

 terior not prominent; scutellum coarsely punctate; elytra expanding 

 apically, the intervals clearly defined and alternately wider, the 

 broader intervals flat, irregularly punctate, the narrower intervals 

 slightly convex and almost impunctate; metasternum clothed with 

 rather long hairs, the abdomen shining and sparsely punctate; 

 pygidium transverse, subconfluently punctate, the punctures not 

 deeply impressed; anterior tibiae with a single external tooth, the 

 apical process elongate and slightly curved, the tooth prominent but 

 obtuse, the larger tarsal claw cleft at tip, the upper ramus (cf ) finer 

 and shorter than the lower, or equal thereto ( 9 "), the larger claw of 

 the intermediate tarsi cleft at tip, the upper process neatly as long 

 as the lower but narrower. Length (cf ) II, (9 ) 13 mm.; width (cf 1 )

 Mesosternal process in the form of a narrow feeble convex ridge; under 



surface glabrous or virtually so; species of small size 17 



7 Pronotum unicolorous. Form oblong-elongate, rather convex, pice- 

 ous, with slightly metallic lustre, the elytra pale brownish-flavate, 

 the suture finely and side margin basally, black; head densely 

 punctato-rugulose, sparsely punctate basally, the eyes (cf ) separated 

 by two and one-half times their width; clypeus flat, broadly trape- 

 zoidal, the apex rather abruptly and moderately reflexed; antennal 

 club (cf ) not quite as long as the stern; prothorax trapezoidal, with 

 feebly, medially subangulate sides, minutely, remotely punctate, 

 the basal bead entire; elytra slightly elongate, sculptured as in 

 flavipennis but more finely, the three narrow smooth intervals very 

 moderately convex; pygidium sparsely and strongly arcuato- 

 punctate; inner anterior claw (cf ) stout, deeply incised at apex, the 

 upper ramus as long as the lower but much more slender, very finely 

 aciculate. Length (cf) 12.0-12.6 mm.; width 6.8-7.3 mm. Hon-

Pronotum unicolorous. Body somewhat as in the preceding but still 

 more elongate, black, slightly piceous beneath, the lustre barely at 

 all metallic; elytra colored as in ochroptera; head (cf ) nearly similar 

 but with slightly more prominent eyes, which are separated by but
