ONSOMEUNDESCRIBED FORMS OF FLORIDA COLEOPTERA, 



BY W. S. BLATCHLEY, INDIANAPOLIS, INDIANA. 



In 191 1 I spent the time from January 8th to April 17th in Central 

 and Southern Florida, and while there collected insects in a number of 

 localities, notably near Sanford, St. Petersburg, Sarasota, Ft. Myers, Little 

 River, and Ormond. The time of year was not the best for the most suc- 

 cessful collecting, as the insects of Florida hibernate in much the same 

 manner as they do farther north, many of them being represented there, 

 as here, during the winter months in the egg, larval and pupal stages. 

 However, about 500 species of Coleoptera were taken, and also many 

 Orthoptera, Hemiptera and butterflies. It is at present my intention to 

 again visit Florida in January, 19 13, and, perhaps, stay later in the spring, 

 making collections in the same orders, and then publish notes on the 

 ••' catch " of the two seasons. Meanwhile, a few forms of Coleoptera, 

 which have apparently hitherto escaped observation, are herewith 

 described. 



Cœlambus 7nargi?npennis, sp. nov. 



Short, rounded, oval, subdepressed above, moderately convex 

 beneath. Head, thorax, under surface, femora and tibiae reddish brown ; 

 elytra piceous-black, shining, with narrow side margins, broadening into 

 a rounded lobe at middle, reddish brown, tarsi and apical fourth of 

 antennae dusky. Clypeus broadly rounded, distinctly margined. Head 

 and thorax finely, evenly but not densely punctate ; the elytra more 

 coarsely, densely and rather shallowly p'mctate. Meso- and meta-sterna 

 coarsely, rather sparsely and deeply punctate, the punctures of abdomen 

 finer and more shallow. Length 2.5 — 2.8 mm. 



Frequent in shallow brackish ponds, one to two miles inland, near 

 Sarasota, Florida. March 1—3. This beetle has the form of C. acaroides 

 Lee, but the elytra are differently coloured, and without the carinas of 

 that species. It is a little larger, more rounded, and much more coarsely 

 punctate than C.farctus Lee. In a few specimens the elytra are mostly 

 wholly piceous, but in the great majority the paler side margins broaden 

 at middle to form a rounded lobe. 



Aphodhis campestris, sp. nov. 



Elongate-oblong, convex. Head and thorax reddish or pale chestnut 

 brown, shining, the latter with front margin darker ; elytra, under surface 



November, 1912
