abdomen more distinctly punctured, legs and coxae rufons. Length .12 — -.14 

 inch ; 3 — 3.5 mm. 



Occurs over the entire region east of the Rocky Mountains 



Varies in color from immaturity to rufous or testaceous. 



C opiciini. Say. — Resembles the preceding in form and color and differs 

 as follows: Thornx minutely transversely strigose or alntaceous between the 

 punctures, elytra with entire basal band red. Length .12 — .14 inch; 3 — 

 3.5 mm. 



Occure more especially in the Gulf States. 



Whether the differences indicated above will be found to be con- 

 stant remains for future determination. The color of the base of the 

 elytra can hardly have much weight and I »have separated our speci- 

 mens entirely by the strigosity of the thorax. 



C scriptiiin, n. sp. — Pale rufo-testaceous, sparsely pubescent, thorax with 

 a spot on each side of middle at base, elytra at ti|) and«discal spot piceous. 

 Antennseas long as thorax, rufo-testaceous. Head and thorax shining, scarcely 

 visibly punctulate. Thorax slightly wider than the elytra, sides regularly 

 arcuate and narrower in front, base truncate, hind angles obtuse. Elytra as 

 long as wide, sides near apex, apex and discal spot behind the middle piceous, 

 surface sparsely punctulate, a row of setigerous punctures near the lateral 

 margin. Abdomen sparsely punctulate, setigerous at the sides, darker in color 

 than the elytra. Body beneath pale rufo-testaceous. Length .08 — .10 inch; 

 2—2.5 mm. 



This species is easily known by the setae, usually six in number, at 

 the sides of the elytra. The color may become piceo-testaceous and 

 the discal spot extend so as to join the apical margin. 



Occurs abundantly from Michigan to Louisiana. 



The sexual characters are very nearly uniform in all the species 

 and are as follows : 



ik/a/c— Anterior tarsi more or less dilated. Sixth ventral segment triangularly 

 emarginate, seventh elongate oval, entire. Last dorsal entire. 



Female. — Anterior tarsi simple. Last ventral elongate oval, fimbriate at 

 middle of posterior margin. Last dorsal quadrifid. 



BOLITOBIUS Steph. 

 The correct arrangement of the species of this genus presents many 

 difficulties, owing to the relative importance to be assigned to the differ- 

 ent characters, the more prominent of which have ah'eady appeared iu 

 the books. Certain departures from the normal form of the maxillary 

 palpi occur in two species, in which these organs become considerably 

 shortened, the joints more robust and often pubescent, especial!}' the 

 third joint. In these also the last joint loses the strictly slender form 

 and becomes decidedly conical as iu Brijoporus. Here therefore is 

 the point where the two genera approach and if the latter genus is to
