humeri and distinctly arcuate, the disk moderately convex, widest behind the 

 middle, the basal fovea short but deep. Abdomen slightly longer and narrow- 

 er than the elytra, the sides parallel and feebly arcuate, parabolic as usual at 

 apex ; dorsal segments equal, the first with two extremely minute basal cari- 

 nse )^ or ^ ss long as the segment and separated by b t little more than ^ 

 the discal width ; between each and the side margin there is a series of small 

 elevated detached granules along the basal margin. Length 0.85 mm. ; 

 width 0.33 mm. 



Texas ( Columbus ). Hubbard and Schwarz. 



The intermediate femora in the male type described above, are 

 greatly swollen, the upper edge very strongly arcuate, the lower 

 feebly sinuate, the tibiae simple ; the fifth ventral is notably short, 

 scarcely visible except laterally, the sixth large, slightly flattened 

 toward the middle and the horizontal pygidium rather large, as 

 wide as long, circularly rounded behind, nearly flat and quite im- 

 punctate. In the female the head is slightly smaller but similar 

 otherwise. Two specimens. 



Texana is closely related to discolor, but differs in color, that 

 species being described as chestnut-brown with the abdomen 

 darker ; discolor is said by LeConte to occur in Louisiana. 



M. Slllcatiila n. sp. — Moderately stout, convex, shining, impunctate 

 and pale brownish-testaceous throughout, the pubescence very short, fine, 

 decumbent and abundant. Jlead slightly narrower than the prothorax, con 

 vex, not quite as long as wide, the eyes small but rather prominent, at slightly 

 more than their own length from the base, the tempora behind them less 

 prominent, slightly convergent and somewhat arcuate to the base ; occiput 

 with a long median channel ; fovese moderate in size, deep, just behind the 

 middle, connected by a deep angulate sulcus, separated by rather less than 3^ 

 the entire width ; supra-antennal prominences pronounced, crossed obliquely 

 by a narrow groove; antennae % longer than the head, slender, the second joint 

 larger and more oval than the first, eleventh very large, conoidal, more than 

 twice as thick as the tenth and as long as the five preceding. Prothorax dis- 

 tinctly wider than long, the sides parallel and almost evenly rounded, strongly 

 narrowed at base, the sides becoming parallel in basal third or fourth ; disk 

 strongly convex, the sulcus deep, strongly angulated at the middle, continued 

 uninterruptedly down the flanks. Elytra distinctly shorter than wide, % 

 longer and % wider than the prothorax, the sides moderately divergent from 

 the slightly prominent humeri to the apex and broadly, rather strongly arcu- 

 ate; intra-humeral fovea deep, evanescent before basal third, the sutural stria 

 fine and feeble. Abdomen rather longer than the elytra and nearly as wide, 

 the sides parallel and feebly arcuate ; apex broadly parabolic ; dorsals equal, 

 the first with two short fine parallel carinse at base, separated by about ^ of 

 the entire width. Length 0.8 mm. ; width 0.3 mm.
