Caelambus princeps, sp. nov. 



Broadly oval, subdepressed above, strongly convex beneath. 

 Head, elytra and narrow front and hind margins of thorax dark 

 reddish or piceous brown; disc of thorax, under surface and legs 

 pale reddish brown; antennae and palpi still paler. Eyes very 

 finely granulate, separated by one and one-third times their own 

 diameters. Clypeus broadly rounded, finely but distinctly mar- 

 gined. Head and thorax finely, sparsely and irregularly punctured; 

 elytra conjointly one and one-fourth times longer than wide, a 

 little more coarsely, more regularly and aciculately punctate.; both 

 they and the under surface very finely and indistinctly alutaceous. 

 Meso- and meta-sterna and abdomen finely, sparsely and irregu- 

 larly punctate, the punctures shallow. Length 4.5 mm.; width 

 2.8 mm. 



Described from a single example taken March 6 from beneath 

 decaying water hyacinth on the southeast shore of Lake Okee- 

 chobee. 



Mr. John D. Sherman, Jr., of Mount Vernon, New York, a 

 special student of the Dytiscidae, to whom the specimen was sent 

 for examination, says, "It is undoubtedly a new and very striking 

 species, in size and shape reminding me of Pachydrus brevis Sharp 

 from Porto Rico."

 chunk half buried in the mud of a tide-water marsh near Sarasota. 



Megilla fuscilabris decepta, var. nov. 



Form of the common fuscilabris Muls. (maculata DeG,.) but 

 smaller. Ground colour above a paler red. Head wholly black; 

 thorax with four small black spots on the basal half, these arranged 

 either obliquely in pairs in the form of a little crown, or with the 

 frOnt pair united behind to form a small V, or with all four united 

 making an irregular crescent which encloses a small red spot in 

 front of scutellum; elytra with the subapical spots of fuscilabris 

 usually united to form a common spot on the suture; tibiae more or 

 less reddish, especially so near base. Length, 5 mm. 



Swept from low herbage. Sanford, March 28; Ormond, April 

 14. Mr. Chas. W. Leng, of New York City, has nine specimens 

 from the Angell collection taken at Key West, Fla., without date.
