Staphylinidce — Fcederus obliteratus. — This beetle is abundant in 

 April. The species occurring on the New Jersey sea-coast, usually 

 determined ob/iteratus, is F. floridaims^ which has likewise the elytral 

 punctures more or less obliterated posteriorly, but very coarse anteriorly. 

 P. obliteratus has a narrower head, longer elytra, with the punctures 

 faintly indicated anteriorly and obsolete behind. It occurs as far north 

 as St. Augustine, to my knowledge. Bledius punctatissimtis occurred as 

 formerly; one of the types of this species was from Southern California, 

 and not that of B./titnatus, as a dislocation by the printer in the former 

 paper makes it appear. 



Laftguria marginipeimis. — Abundant by sweeping weeds. April. 



Cucujldte — Catogenus 7- u/u s. —Tht larva of this widely-distributed 

 species is eminently a wood borer, and in Southern Florida completes its 

 transformations in about three months. Two mature beetles, in length 

 .22 and .45 inch, respectively, were cut, April 25th, from sea grape 

 (Coccolobus) killed by the December frost. The young larvae started 

 out about two inches apart, pursuing parallel routes for 23 inches before 

 pupating. The beetles were over an inch from the surface, and no 

 provisions had been made for their liberation. For the first ten inches of 

 their course their burrows were eaten from the wood just beneath the 

 bark and packed with borings: the remainder of the burrows, also firmly 

 packed, were in the solid wood. The larva of the small beetle had the 

 same supply of food as that of the larger. Why the disparity in size ? 

 And why burrow the same distance ? 



Cryptoviorpha desjardinsi. — Several examples of this graceful 

 species were taken in April in the unfolding leaves of the Banana killed 

 by the December frost, and in a state of semi-putrefaction. The larvae 

 and pupae were seen in the cellular structure of the leaf beneath the 

 epiderm. The Florida examples are identical in form, size and color- 

 ation with those from British Columbia. 



Scarabceidce — Euphoria inelajicholica occurred abundantly, March 

 ist, on thistles (cirsium) — Trichius delta, many examples occurred, May 

 ist, on the blossoms oi iht wWd oWve. {Olea ajtiericatia). It extends to 

 the extreme south of Florida, having been taken at Key West. 



Leptostyius, n. s. — This is a small species, .16 to .20 inch in length, 

 of an ashy-gray colour, and but slightly depressed ; the antennae are 

 conspicuously annulated; the thoracic tubercles are close to the base and 

 in some examples acute, as in Liopus ; the elytra are obliquely truncated
