it differs in its greater lustre and by the males of latter having the 

 elytral apex appendiculate. 



M. mi rami us, Lee. (JETapalorhinus) Proc. Acad. 1859, p. 75. — Head black, 

 front slightly impressed, smooth, shining. Antennae black, strongly pectinate 

 in the males, serrate in the females. Thorax smooth, shining black, sides and 

 occasionally apex, broadly margined with yellowish red. Elytra scarcely 

 shining, variable in color from ochreous to blue, frequently of the former color 

 clouded with the later. Apex paler and smoother, appendiculate in the males. 

 Body beneath black, tinged with blue. Legs black, hind tibise and middle 

 knees yellowish. Length .16 inch; 4 mm. 



There need be no difficulty in distinguishing this species from the 

 preceding, by the color of the hind tibiae alone, even in doubtful 

 cases. In some unusually large specimens the aspect is that of 

 auritus, but there are many characters serving to distinguish the 

 latter. 



This species is widely distributed in California, but most abundant 

 at Fort Tejon on the flowers of various Leguuiinosae. 



IH. Ulkei, n. sp. — Black, feebly shining, sparsely clothed with cinereous 

 pubescence. Head black, with slight vertical impression. Antennae black, 

 strongly pectinate from the fourth joint, third joint triangular. Thorax 

 broader than long, sides fully rounded, surface punctulate and sub-opaque, 

 sides broadly margined with yellow. Elytra black, feebly shining, surface 

 scabrous, sides parallel, broadly rounded at tip. Body beneath black, shining. 

 Legs black. Length .14 inch ; 3.5 mm.

Caphalistes, Motsch. Bull. Mosc. 1859, pt. iv., p. 209. 



This genus appears to occupy an intermediate position to the Mala- 

 chii on the one hand and the Attali on the other, not only in the 

 position of the antennae but also in the form of the anterior tarsus of 

 the male. The latter is described by LeConte as having the first 

 two joints thicker than the following, and by Motschulsky as longer. 

 Both of these facts are true, but the second joint is very distinctly 

 prolonged over the third, although to a very slight extent. The two 

 species vary in the structure of the abdomen. 



T. abdominalis, Lee. Proc. Acad. 1859, p. 74.— Black with slight tinge 

 of blue, shining, sparsely clothed with short black hairs. Head elongate, 

 front slightly impressed, anterior margin of epistome membranous. Antennas
