than long, feebly convex, very minutely and densely punctate and pubescent. 

 Legs moderate ; femora fringed with fine erect pubescence, the flat surfaces 

 with very small, recumbent, squamiform hairs not very densely placed ; tarsi 

 as long as the tibiae ; claws arcuate, finely attenuate ; tooth of anterior claw 

 of anterior tarsi erect, near tlie base, sliglitly arcuate, stout and scarcely one- 

 third as long as the remainder ; tooth of the posterior claw, less tlian one-half 

 as large, projecting but slightly above the basal carina ; proportions in the 

 other claws nearly similar, the tooth of the posterior claw of the hind tarsi, 

 on its outer edge, nearly one-fifth the internal length of the remaining portion ; 

 corresponding ratio of the anterior claw one-third. Length 22.0 mm. 



California (Los Angeles Co.). 



The diagnoses here given are taken from the male ; in the female 

 of the present species the tarsal claws are rather smaller, the teeth 

 more nearly equal, the greatest difference being in those of the 

 anterior tarsi, the posterior being almost absolutely equal. 



In Thyce the fourth palpal joint is received at base in a broad 

 excavation in the apex of the robust transverse third joint, and the 

 latter in turn is similarly connected with the second. 



The proportional length of the fourth palpal joint in pulverea is 

 the same as that given for palpalis, but the two species can be dis- 

 tinguished by the apparently denser pubescence of pulverea, by 

 the more robust palpal joint in which the groove, according to the 

 figure given by Dr. Horn, is differently shaped, and by the claws 

 of the posterior tarsi, in which the teeth are said to be very nearly 

 equal in palpalis (Trans. Am. Ent. Soc, VIII, p. 147). 



T. fossiger n. sp. — Form rather broadly oval, convex, castaneoxis ; head 

 and prothorax piceo\is ; vestiture throughout nearly as in jmlcerea, but 

 slightly coarser, and with the erect hairs of the pronotum decidedly longer. 

 Head small, wider than long; olypeus concave, truncate; angles narrowly 

 rounded ; sides parallel, strongly arcuate ; antennal club slightly shorter than 

 the stem and but very slightly longer than the fourth palpal joint, the latter 

 elongate, rather slender, the apex distinctly deflexed, and with the usual 

 minute circular truncation, one-third longer than the three preceding together ; 

 external groove entire, very narrow and deep, slightly enlarged near the base, 

 and again much more feebly so near the apex. Prothorax two-thirds wider 

 than long ; sides laterally strongly angulate, the angle rounded ; sides very 

 feebly sinuate anteriorly, feebly arcuate toward base and nearly coarctate with 

 the latter, the basal angles being very obtuse and broadly rounded ; apical 

 angles right, not rounded ; apex veiy feebly emarginate, one-half as wide as 

 the base, the latter broadly, feebly angulate, the angle broadly rounded ; disk 

 convex, even, finely, feebly and densely punctate. Elytra two-fifths longer 

 tlian wide and two-fifths wider tlian the prothorax ; sides feebly arcuate ; 

 apex broadly angularly emarginate ; humeri very feebly tumid ; disk with
