AMERICAN COLEOPTERA. 105 



T. nanus. Er. — Pitchy black, apical third of elytra rufo-testaoeous. ITead 

 black, antennae piceous, basal joints paler. Thorax slightly broader than the 

 elytra, pitchy black, sides and base narrowly paler. Elytra similar in form 

 to chryaomclinus but more distinctly punctured. Body beneath, femora and 

 coxae pitchy black, tibiae and tarsi piceo-testaceous. Length .12 — .14 inch; 

 3— .3.5 mm. 



By its color this is one of the most distinct species in our fauna. 



Occurs from Canada to Pennsylvania. 



T. SCitnln!^, Er. — Pitchy black, shining, apices of elytra testaceous. Head 

 black, antennae rufo-testaceous. Thorax slightly broader than the elytra, pitchy 

 black, lateral and apical margins narrowly paler. Elytra very slightly broader 

 than long, apical margin testaceous, a piceous spot at humerus, surface dis- 

 tinctly punctulate, sparsely pubescent. Abdomen piceous, sparsely punetulate 

 and pubescent. Body beneath piceous. Legs testaceous, anterior coxas darker. 

 Length .10 inch; 2.5 mm. 



One specimen from Louisiana is referred to this species. In form 

 it resembles hrnnneus but is less depressed and the third joint of the 

 maxillary palpi is less dilated. 



T. brunnous. Fab. — Rufo-testaceous, form depressed, elongate. Head 

 piceous, antennae testaceous. Thorax twice as wide as long, not wider than 

 the elytra, sides gradually narrowing to apex. Elytra as wide as long, sparsely 

 punctulate and pubescent. Abdomen slightly darker than the elytra, similarly 

 punctured. Body beneath rufo-testaceous, metasternura somewhat darker. 

 Legs and coxae testaceous. Length .10 — .12 inch; 2.5 — 3 mm. 



It may easily be noticed that the penultimate joint of the maxillary 

 palpi is more inflated than in any other of the genus. 



Occurs over our entire country including California, is also common 

 in Europe and Northern Africa. Probably cosmopolitan. 



CII.EA Duval. 



Owing to the discovery of several new Tachinus with characters 

 slightly at variance with the majority of the species, the diflFerences 

 between these two genera seem to be narrowed down to a slight carina- 

 tion of the mesosternum between the coxae, and the tarsi simple in 

 both sexes. The first joint of the hind tarsus is, it is true, nearly 

 as long as the three following united, but in Turliinua tarhi/poroldes 

 the same joint is very nearly as elongated. Cilea has priority over 

 Leucoparyphus. 



One species only is known in our fauna occurring especially in the 

 Northern States and common in the greater part of Europe. L. dis- 

 coideus (Mels.), Lee, should be placed in Tachinus, the mesosternum 

 being simple and the anterior tarsi dilated in the male.
