254 THE CA.NADIAN ENTOMOLOGIST. 



Dytiscidce — Hydrophilidce. — The species listed were taken alive on 

 the ocean side of the lake, and, with one exception, had probably fallen 

 into it during a nocturnal flight from some fresh water lake on the main 

 land. However, Philhydrtis simplex was quite abundant under stones and 

 sticks on the shores of the lake, and the night of the loth of March being 

 damp and sultry, a flight occurred, many coming into the house to the 

 light. This form, though only. 09 to. ii inch in length, is united with 

 the northern ochraceus. Gyrinidce were seen in abundance in a small lake 

 on the main land. 



Staphylinidce--Belonuchus formosus, var. This variety was very 

 abundant at all times in rotting oranges and under damp rubbish ; it 

 differs from the typical form in being altogether rufous, except the last 

 two abdominal segments, black. No intermediate forms have been met 

 with, and Mr. Schwarz states it occurs abundantly over all Florida. 



Tachyponts, sp. — Two examples were taken under pine bark, greatly 

 resembling my examples of T. scituhis from Sweden ; the thorax and elytra 

 are identical in coloration, but are not perceptibly punctured when viewed 

 with a lens ; the abdomen is more finely margined, and the length is only 

 .06 to .07 inch. Blediiis punctatissij?ius, and B. basalis. — The latter 

 inhabits the wet sand bordering the lake in countless multitudes, and 

 with it the former, but in much less abundance. B. fumatus was not 

 seen till April ist, and afterwards rarely. One of the types of this species 

 was from Southern California. 



Brachypeplus glaber — Five examples of this curious and still rare 

 beetle were taken under the bark of a dead, standing pine, with Cossomis 

 impressifrons. Previously I had one example taken near St. Augustine, 

 and the types were from Enterprise, Florida ; according to Mr. Schwarz, 

 no others are known in North American collections. 



Mycetoph'tgidce — Belonging to this family several examples were 

 taken in April, of what may, perhaps, be new either generically or 

 specifically, or both. They were sheltering in the folds of Palmetto 

 leaves, on the blossoms of which Mr. Schwarz took them abundantly, 

 both at Lake Worth, and also at Biscayne Bay, and also the larvae under 

 the bark of various trees ; and he also states that it occurs in the West 

 Indies, in Costa Rica, and was taken at the Chicago Exposition, in dried 

 fruits (or seeds ?) from Central America.
