the elytral spots, leaving only a pale lateral margin which broadens into a 

 rounded lobe at the middle. Blatchley in his description says there is no elytral 

 carina, it is however, quite as distinct in a typical example before me as in the 

 usual acaroides form. 



The types of acaroides were from Illinois and Kentucky. Specimens 

 before me are from Illinois ; Miss ; Fedor, Texas ; Winnfield La. 

 (Pilate.) It is reported from Cincinnati, Ohio, by Dury, and is on the 

 Iowa List(Wikham.) The variety occurs in Florida (Sarasota and 

 Dunedin Blatchley. ) 



The front and middle tarsi of the male are distinctly dilated, and 

 there is in this sex a small discal excavation of the last ventral from 

 the anterior margin of which project backward two approximate 

 porrect slender spines. This remarkable structure exists in the follow- 

 ing species, but so far as I know has no parallel elsewhere in the 

 family, and seems to have been entirely overlooked. 



C. farctus Lee. 



Rotundate oval, feebly shining above, opaque beneath, general color reddish 

 brown, the elytra darker brown with the side margins suffusedly paler, outer 

 joints of antennae, tarsi and frequently the basal half of the abdomen more 

 or less infuscate. Head not margined in front, finely densely punctate. 

 Prothorax similarly punctate, a few interspersed coarser punctures along the 

 base. Elytra finely, closely punctate, with numerous intermixed coarser ocellate 

 punctures in the basal half, these becoming less numerous or nearly disappearing 

 posteriorly. Body beneath very densely punctate, the ventral segments very 

 minutely so, the metasternum and coxal plates more coarsely so. Length 2.2 

 to 2.3 mm.; width 1.35 to 1.4 mm. 



Le Conte's type was from Massachusetts, and all the specimens at 

 hand are from Tyngsboro, Mass., where I have taken it somewhat 

 sparingly in a small woodland pond. Crotch recorded it from New 

 Jersey also and recent collectors report its occurrence at Lakehurst 

 in that state. 



The four anterior tarsi are quite distinctly dilated in the male, 

 evidently narrower in the female. The last ventral of the male shows 

 the same median excavation and porrect spinules as in acaroides, but 

 the excavation is here rather larger and the spinules less approximate. 



C. punctatus Say. 



Broadly rotundate ovate ; very convex, especially beneath, head thorax and body 

 beneath rufotestaceous, the elytra usually duller brownish yellow, the disk with 

 obscure fuscous markings which are sometimes feebly defined, but usually 

 broadly suffused; base and apex of thorax blackish; antennae and legs entirely 

 rufotestaceous. Punctuation above strong, close and nearly uniform, beneath 

 coarse and close. Tarsi narrow, not appreciably broader in the male. Length 

 2.8 to 3 mm.; width 1.7 to 1.9 mm. 



A common and well known species widely dispersed in Canada and 

 the northern half of the L^nited States from New England to the
