HARPALIISLE 257 



deeply impressed, the scutellar wholly wanting as usual; intervals 

 feebly convex, more strongly suturad; hind tarsi slender, the first 

 three joints decreasing uniformly and moderately in length, the 

 fifth as long as the first two or 2-4 combined. Length ( 9 ) 3-8 mm. ; 



width 1.3 mm. Texas (Austin) suavis n. sp. 



Form rather more parallel and less convex, shining, piceous-black, the 

 prothorax and elytral suture generally slightly paler; under surface 

 nearly black, the epipleura pale; legs piceo-testaceous; head three- 

 fourths as wide as the prothorax, with large though only moderately 

 prominent eyes; antennae very slender, fully half as long as the body, 

 blackish, paler basally; prothorax rather transverse, fully a third 

 wider than long, the apex feebly sinuato-truncate, with obtuse but 

 rather sharply defined angles and a little wider than the base; sides 

 almost evenly rounded, a little more converging and less rounded 

 posteriorly; base transverse medially, the angles very broadly 

 rounded, not at all deplanate, the foveae rounded, shallow, isolated 

 and rather strongly and closely punctate; stria strong, entire; elytra 

 rather more than one-half longer than wide but only a third wider 

 than the prothorax, of the same form as in suavis and similarly 

 striate; discal puncture at three-fifths; hind tarsi similar but with a 

 slightly longer basal joint; male with the anterior tarsi distinctly 

 dilated; joints 2-4 strongly transverse, triangular and broadly 

 emarginate. Length (cf 9 ) 3.9-4.2 mm.; width 1.2-1.3 mm. 

 Kansas (Sedgwick Co.) and Texas. Three examples, .festinans n. sp. 



The species from Sonoma, Cal., identified above as symmetricus 

 Mots., agrees in every particular with the original description, 

 including size of the body; the locality also is virtually identical. 

 The large series of tantillus at hand, by reason of certain diversity of 

 coloration, length of elytra, length and thickness of antennae and 

 other features, seems to indicate that there may be some distinct 

 species or subspecies that are now confused, but further extended 

 series from carefully recorded localities would be desirable before 

 coming to any definite conclusion. I am unable to identify the 

 male of tantillus from tarsal characters, the anterior tarsi being 

 undilated in all the numerous examples examined, but the male 

 may be relatively rare. Larvatus is allied to rivalis and is similar 

 in its peculiar pallid coloration and very prominent eyes, but the 

 size is very much smaller, the head relatively larger, the antennae 

 shorter and more slender and the sides of the prothorax not sinuate 

 toward base as they are in rivalis. Neglectus is unknown to me and 

 I have simply transcribed the original characters. Bradycellus 

 nigriceps of LeConte may be a Tachistodes and allusion will be 

 made to it under that genus.
