mate each other very closely. The type of flavicolle does not seem to 

 be a fully developed specimen of the species to which it belongs. It 

 must also be seen that Ivirby's description of the thorax hardly corres- 

 ponds either with itself or with ovx flavicolle where he writes " camp- 

 anulate — and very short." Kirby's description may be found in Lia- 

 nean Transactions, sii, p. 424. 



Mycetina pallida, n. sp, — Elongate, pale rufo-testaceous, moderately shining. 

 Thorax sparsely and very finely punctured, longitudinal and basal impressions 

 well marked. Elytra less shining, very finely but sparsely punctured and 

 with minute hairs. Beneath more distinctly punctured, paler ; prosternum 

 narrow, depressed. Legs slightly darker than the under surface; antennas 

 brownish. Length .26 inch ; 6.5 mm. 



A female specimen in the cabinet of Dr. Leconte, received by Dr. 

 S. Lewis, from Colorado. 



Eesembles in form M. Iseta (Lee.) and not differing from that 

 species in the relative size of its parts. Differs from all our species in 

 its entirely uniform pale rufo-testaceous color. The elytra are some- 

 what more opaque than the rest of the surface and under high power 

 are very finely alutaceous, and with rather sparsely placed fine punc- 

 tures, each bearing a minute slender hair. 



M. limbata, u. sp.— Piceous black, shining ; entire upper surface with fine 

 sparsely placed punctures, each bearing a very minute hair, those of the thorax 

 less distinctly imjiressed ; transverse and longitudinal impressions of thorax 

 distinct tliough not deep. Elytra piceous black, entire margin from humerus 

 to apex testaceous and with a narrow band extending inwards from the middle 

 of margin slightly obliquely towards the suture without attaining it. Antennse 

 not closely articulate and with the palpi, ferruginous. Under surface black, 

 Bub-opaque, more coarsely j^nnctured than the iipper surface. Legs ferrugin- 

 ous. Length .18 inch; 4.5 mm. 



This species has exactly the forui of Emlomychus higuttatus^ and may 

 be easily distinguished from any of our species of Mjjcetlna^ by the 

 system of coloration. Belongs to same group with perpiilchra in which 

 the mesosternum is broader than long and sub-pentagonal. The pale 

 margin of the elytra becomes much broader toward the apex and ex- 

 tends slightly along the suture. 



Occurs in California. For the unique in my cabinet I am indebted 

 , to Mr. James Behrens, of San Francisco. 



Epipocus unicolor, n. sp. — Rufo-ferrugineus, sparsely clothed with short 

 golden hairs. Head rather densely and coarsely punctured. Thorax one-half 

 broader than long, deeply emarginate in front, angles obtuse; sides rounded in 

 front of, sinuate behind middle, hind angles acute, moderately prominent; disc 

 coarsely but rather sparsely punctured between grooves, more finely and densely 

 toward the sides ; grooves moderately deep and slightly convergent and ex- 

 tending two thirds toward apex. Elytra broader at base than thorax, moder-
