 pi. III. fig. 12. 



Also closely allied to americanus, but differing by having the outer 

 thoracic stria wholly absent; the elytral striae finer, the fifth joining the 

 sntural ; surface smooth. Length 3.5 mm.

lir.O (3510). HISTEB NUBILUS Lee., Col. of Kansas, 1859, 7. 



Broadly oval, subconvex. Thorax with inner stria entire; the outer, 

 short, apical. Elytra with four entire stria 1 ; fifth short, apical; sutnral 

 extending in front of middle. Front tibi.'e with four teeth, the apical <nn> 

 slightly bifid. Length 5 mm. 



A well marked species described from Kansas and represented 

 in the collection by a single specimen taken in Vigo County, June 7, 

 from beneath the carcass of a dead hen. 



11G1 (3511). HISTEB POLIAJTUS Lee., Col. of Kansas, 1859, 7. 



Resembles nulnhis, but differs by being less broad and by having the 

 fourth dorsal short, basal only, or with a few disconnected punctures at 

 apex. p]pipleura with three stria?. Apical tooth of front tibiae larger. 

 Length 5 mm. 



Lake and Crawford counties: rare. May 13 May 25. 



GROUP D. 



To this group belongs a single small species, separated from its 

 allies by the characters mentioned in key. 



11(52 (nr.02). HISTEB SERVUS Erichs., Jahrbuch, 1834. 147. 



Oval, convex. Thorax with two marginal stride, the outer usually entire, 

 sometimes abbreviated to one-half or three-fourths. Elytra with four entire 

 striae, fifth short, apical; sutural half the length of elytra; subhumeral en- 

 tirely absent. Pygidium convex, coarsely and rather densely, propygidium 

 more densely and more coarsely, punctured. Front tibiae with three teeth, 

 the apical one deeply bifid. Length 3.5-4.5 mm. 



Vigo County; scarce. May 20-June 11. H. defect us Lee., is 

 probably a synonym of servus, as the two are separated on the length 

 of the thoracic stria, which varies exceedingly in the specimens of 

 tennis before me. 



SUBGENUS II. (PHELISTER.) 



Very small, oval species, having the inner thoracic stria absent, 

 .he outer sometimes present and then very close to margin; proster- 

 num with a stria on each side; mesostermun prominent in front. Of 

 I he six species known from the United States, two occur in Indiana.
