side pieces as in the other Quediitii, while in the Tachyporini the coxse 

 are free in their entire length. 



T. collaris Er., Staphyl. p. 289. — Head oval, smooth, shining, two punc- 

 tures over each eye. Antennae geniculate, longer than the head and thorax, 

 slender. Thorax broader than long, narrowed in front, sides feebly base more 

 broadly arcuate, disc with .two punctures one-third from apex, two at the 

 apical margin, others smaller and distant along the lateral and basal margins. 

 Scutellum moderately densely and finely punctulate. Elytra conjointly a little 

 wider than long, surface densely and finely punctulate and finely pubescent. 

 Abdomen rather coarsely punctate. Length .14 inch; 3.5 mm. 



The colors of this species are: head black, antennae rufo-piceous, 

 paler at tip and base, thorax bright rufous, scutellum rufous, elytra 

 piceous, apical margin narrowly rufous, abdomen rufo-piceous, legs 

 testaceous. The thorax may become darker. 



Specimens were collected at Haulover, Florida, by Messrs. Hubbard 

 and Schwarz, which agree with Erichson's description of the species 

 as found in Venezuela and Guiana. 



ACYLiOPHORUS Nordm. 



There are but few special characters among the species of this 

 genus. 



The head is oval, slightly longer than wide, with four punctures 

 in a line on each side, two over each eye and two others posteriorly. 

 Behind the eyes are numerous punctures with short pubescence, except 

 \n jiavipes in which that part is nearly smooth. 



The labrum is truncate. 



The eyes are oval, longer than wide, the anterior margin sub- 

 truncate in most of the species and very narrowly separated from the 

 base of the mandibles; pratensts however has the eyes rounded in 

 front and distant from the base of the mandibles. The infra-orbital 

 ridge although present is very feebly developed. 



The antennae, equal the head and thorax in length, slightly or very 

 decidedly {JIavipes) thickened externally and with the second joint 

 always longer than the third. 



The thorax is broader than long, narrowed in front, and on each 

 side of middle in front two punctures, one at the margin the other 

 one-third behind it. 



The anterior tarsi are stouter than the others, the first four joints 

 short and indistinct, the fifth as long as these together, bearing stout 

 feebly curved claws. The middle and posterior tarsi are slender and 

 have disproportionately small claws. This difi'erence in the claws is 

 not sexual.
