194 MEMOIRS ox THE COLEOPTERA 



arcuate; sinus feeble but distinct; striae nne/the scutellar long, usually 

 free; intervals flat throughout (9) or nearly so (cf), the entire 

 surface with traces of excessively minute punctulation, not visible 

 in the female, the lateral line of fovese subinterrupted medially, the 

 discal puncture strong, at apical fourth; hind tarsi slender, glabrous 

 above, the first joint fully as long as the next two and much longer 

 than the fifth; spur of the anterior tibiae very slender and simple. 

 Length (c? 9 ) 10.0-10.8 mm.; width 3.8-4.3 mm. Rhode Island to 

 Iowa. Abundant. [Selenophorus lugubris Dej. (9); Harpalus 

 manhattanis Csy. ( 9 )] lugubris Dej. 



For some reason, not stated, this species was not considered by 

 Dr. Horn in his sketch of Anisodactylns (Proc. Am. Phil. Soc., 

 1880, p. 162), though there is better reason for considering it a 

 part of that genus than there is to include Dicheirus. The female 

 type was placed in Selenophorus by Dejean, solely because of the 

 very slender ligula and absence of mentum tooth, but the three 

 series of elytral punctures constitute a more decisive generic mark 

 of Selenophorus than the structure of the mouth parts. The fact 

 that no one, observing solely the female, would probably think of 

 placing the species in Anisodactylus, is at least one reasonable proof 

 of its generic isolation. 



Amphasia Newm. 



In this genus, which is again monotypic, the mouth parts are 

 almost exactly as in Xestonotus, 'the ligula being very slender and 

 not in the least expanded at apex and the paraglossae fully as long, 

 rather broad and obtuse at apex, but otherwise, and especially in 

 type of coloration and sculpture, which may become of generic 

 significance in some groups of Carabidae, there is no similarity 

 whatever. The type of Amphasia may be described as follows: 



Form oblong, rather feebly convex, shining throughout in both sexes, 

 pale testaceous in color throughout the body, legs and trophi, except 

 that the elytra are dark brown and the entire sterna and parapleura 

 of the hind body deep black; head rather small and long, one-half 

 as wide as the prothorax, the neck somewhat constricted behind the 

 moderate though very prominent eyes, the foveae very small but only 

 moderately deep and elongate-oval; antennae slender, rather pale 

 brown, the two basal joints paler and testaceous; prothorax two- 

 fifths (cf 1 ) to one-half (9) wider than long, the sides parallel and 

 evenly, somewhat strongly arcuate; apex deeply sinuate, with 

 advanced and only rather narrowly rounded angles and distinctly 

 narrower than the base, which is transverse, rounding laterally, the 

 angles very broadly rounded, the fine basal bead usually broadly
