98 AMERICAN COLEOPTERA. 



the Pacific Coast versicolor is rarely found south of Central 

 California ; pictum is known to me from Louisiana to South- 

 ern California. 



Unfortunately, as has already been pointed out in the 

 books, the name pictum is preoccupied, and we must use 

 Motschulsky's name flavopictum for this species. 



HYDROPHILID^E. 

 CRENIPHILUS Mots. 

 At the time of Dr. Horn's synopsis of this genus in 1890, 

 a single species only — degener — was known with 7-jointed 

 antennas. This extreme reduction in the number of joints 

 was commented upon as being quite remarkable, and it is 

 certainly not less so that of the four new forms discovered 

 since Horn wrote, all, without exception, possess this peculi- 

 arity. Of these four, one — elegans — has been previously 

 described ; the others are now made known. 



C. lodingi n. sp. 



Oval, moderately convex, very slightly less than twice as long as 

 wide, black, not or but very faintly aeneous, lateral margin with a 

 sharply defined pale border, narrow on the prothorax, becoming wider 

 toward the apex of the elytra, where it involves about one-fourth or 

 one-fifth of the sutural length. Antennas, palpi and legs pale, except 

 the femora, which are in great part dusky. Punctation of elytra coarse 

 and rather close, the punctures separated by from a little less to a little 

 more than their own diameters ; head and prothorax somewhat more 

 finely punctate. Body beneath blackish, opaque, finely pubescent : 

 front and middle thighs pubescent ; hind thighs glabrous, impunctate 

 and without strigosity ; hind tarsi and tibiae subequal in length, the 

 latter possibly a trifle longer. Prosternum carinate ; mesosternal keel 

 strong. Length 2.3-2.5 mm. 



Mobile, Alabama. 



Described from a series of nine examples collected and 

 given me by Mr. H. P. Loding, to whom it is a pleasure to 

 dedicate the species in recognition of his painstaking and 

 very successful efforts in collecting the smaller and more 

 obscure species of his fauna. 



The present species is remarkable, first for its 7-jointed 

 antennae, and again for its very close affinity to C. elegans of 

 California. The two are virtually identical in every respect
