R.UTELIN/E 31 



traceable across the middle, the lobe broad and moderate; surface 

 at base not sloping toward the bead, minutely, remotely punctulate 

 throughout; scutellum more strongly and less sparsely punctate; 

 elytra barely a fourth longer than wide, rather inflated, more than 

 one-half wider than the prothorax, rapidly rounding behind in about 

 apical third; punctures not very fine but shallow and inconspicuous, 

 sparse in rather even and widely spaced lines, the second interval 

 very broad, sparsely and confusedly punctate; pygidium with the 

 arcuate scratches feeble and sparse; inner anterior claw differing 

 completely from the preceding, rather stout, feebly and subangularly 

 prominent beneath behind the middle, very coarsely and deeply 

 cleft at apex, the upper ramus not differing very much from the 

 lower, both rather deflexed, unusually diverging and very acute at 

 apex, the upper distinctly shorter than the lower. Female smaller 

 and narrower than the male as in flavipennis, the antennal club 

 small, much shorter than the stem, the eyes smaller and much less 

 prominent; larger anterior claw slender, subevenly bifid at apex. 

 Length (cf 9 ) 8.4-9.2 mm.; width 4.6-5.4 mm. Arizona. Two 

 specimens moquina n. sp. 



17 Elytra pale, with fasciate maculation, never entirely black; larger 

 anterior claw different in the sexes 18 



Elytra usually deep black throughout, when pale rarely having fasciate 

 but rather longitudinal and very feeble marking; larger claw similar 

 in the sexes 20 



1 8 Pronotum wholly dark in color. Body elongate-oval, rather convex, 

 shining, blackish, the under surface and legs piceo-rufous; elytra 

 tawny-yellow, the sutural interval and external bead blackish, the 

 disk with a transverse irregular black fascia before the middle, 

 uniting with a large humeral black area; head, pronotum and scu- 

 tellum with distinct metallic lustre; head with separated punctures, 

 smaller basally, except in a medial anterior frontal pit, which is more 

 densely punctate, the clypeus trapezoidal, twice as wide as long, with 

 broadly rounded angles and rather feebly reflexed edges, its surface 

 densely punctato-rugose, somewhat impressed medially along the 

 suture; eyes moderate; prothorax not quite twice as wide as long, 

 the sides evenly rounded and converging from base to apex, the latter 

 sinuate, with sharp prominent angles; base broadly and feebly 

 lobed, the bead strong and entire, the angles not very broadly 

 rounded; surface finely but distinctly, sparsely punctate throughout; 

 scutellum sparsely and a little more strongly punctate; elytra with 

 even impressed series of moderate punctures to the sides, the second 

 interval wide, irregularly and subbiseriately punctate along the 

 middle; fourth and sixth with single series of smaller punctures, 

 3-5-7 moderately costuliform and smooth; pygidium dark, shining, 

 convex, having the wavy scratches deep and rather closely anasto- 

 mosing, under surface glabrous. Length (9) 8.5 mm.; width 4.3 

 mm. Honduras (San Pedro Sula) *crucialis n. sp. 



Pronotum never wholly dark, always at least pale along the sides. ... 19 



19 Elytra each always with a small rounded dark spot near the apical 

 margin and at some distance from the suture, this being the only
