2o MEMOIRS ox THE COLEOPTERA. 



California, which belong not only to the type of the two preceding 

 species but closely resemble them, to such a degree in fact that it 

 is scarcely worth while to describe them at present. 



Atheta iterans n. sp. Rather dull, the abdomen more shining, not very 

 stout, parallel, only moderately convex, piceous, the head black; elytra and 

 legs more or less pale brownish; abdomen black, paler basally and at the 

 apices of the first three segments ; antennae inf uscate ; pubescence very short, 

 close, inconspicuous; head convex, not distinctly punctate, the eyes not 

 prominent; carinae fine and feeble but entire; antennae moderate, subparallel, 

 the outer joints distinctly wider than long; prothorax transverse, much 

 wider than the head but only a little narrower than the elytra, widest before 

 the middle, the sides straighter basally; median line finely and feebly im- 

 pressed ; elytra wider than long, distinctly longer than the prothorax, minutely, 

 densely punctulate; abdomen much narrower than the elytra, parallel 

 throughout, minutely, not closely punctulate, the first three tergites strongly 

 impressed at base; mesosternal process triangular, finely aciculate but not 

 much prolonged at apex, extending to beyond the middle of the coxae, which 

 are contiguescent, its tip far from the apex of the angulate metasternum; 

 first four joints of the hind tarsi equal. Length 2.8 mm.; width 0.6 mm. 

 New York (near the city). 



Distinguishable by the abdominal and sternal structure and the 

 fine impressed median line of the pronotum. Sexual characters 

 are not evident in the types. The fifth tergite is slightly longer 

 than the fourth. 



Atheta enitescens n. sp. Rather slender, moderately convex, strongly 

 shining and minutely, sparsely punctulate, the short stiff vestiture not dense 

 even on the elytra; body piceous-brown, the head and abdomen black, the 

 elytra slightly paler than the prothorax, the legs pale, the antennae blackish ; 

 head well developed, the eyes rather prominent, at a little less than their 

 own length from the base; carinae fine but entire; antennae rather long, 

 gradually and feebly incrassate, the outer joints but slightly wider than long; 

 prothorax distinctly wider than the head and correspondingly narrower than 

 the elytra, two-fifths wider than long, the sides subparallel, broadly, evenly 

 rounded, the basal angles much rounded; surface finely, feebly impressed 

 along the median line; elytra slightly transverse, much longer than the 

 prothorax, the asperate punctures distinct but not very close-set on the pol- 

 ished ground; abdomen much narrower than the elytra, parallel throughout, 

 minutely, sparsely punctulate, the fifth tergite distinctly longer than the 

 fourth; mesosternal process extending to apical fourth of the coxae, drawn 

 out but not very finely pointed, its tip separated by a long distance from 

 the metasternum, which is extremely short and very broadly rounded ; basal 

 joint of the hind tarsi shorter than the second. Length 2.0 mm.; width 

 0.5 mm. New York (Ithaca). 



The male sexual characters of this small species are remarkably 

 distinct, the sixth tergite being densely micro-reticulate and with
