Ili/droph'dus sti-iatus Melsh. Catal. [189] 



Head dark greenisli, with a cupreous gloss : thorax tinged 

 with rufous, with a double, longitudinal, abbreviated line : scutel 

 black : elytra with acute, closely punctured striae ; a small spot 

 on the humerus, and two others arranged in a very oblique series, 

 with respect to the first; then a transverse, much undulated 

 series of five or six small spots ; then two small spots near the 

 sutural tip, black : beneath blackish : feet pale rufous. 



Length more than one-fifth of an inch. 



About equal in size, and closely allied to the 2^^f''!]f^'i'>ii(s of 

 Herbst, but that species is represented to be altogether destitute 

 of the black spots on the elytra, and of the double thoracic line. 



[Belongs to Berosus. — Leg.] y 



3. H. EXIQUUS. — Pale testaceous; elytra with punctured 

 stria3. 



Body with numerous small punctures : head with the trans- 

 verse line very distinct : elytra rather paler than the thorax, 

 with the striae rather obtuse, punctured : beneath slightly tinged 

 with rufous. 



Length one-tenth of an inch. 



This small species I obtained on the sea shore of Chiucoteague 

 Island. 



[I have not identified this species. — Leg.] 



4. H. SUBCUPREUS. — Black, obsoletely tinged with cupreous ; 

 elytra destitute of striae, excepting the sutural one. 



Hi/drophilus minutus Melsh. Catal. 



Body oval, punctured, black, with a slight cupreous reflection : 

 thorax obsoletely piceous on the lateral margin : elytra with 

 rather larger punctures than [190] those of the head and tho- 

 rax; striae none, excepting the sutural one, which is obsolete in 

 the middle, and does not approach the base ; exterior margin and 

 tip obsoletely piceous : beneath blackish-piceous : feet piceous. 



Length much less than one-tenth of an inch. 



Closely allied to the genus Sph-xridium. It is much smaller 

 than the minutus of Herbst. 



[A species of IL/drohius, having S-jointed antennae. — Leg.]
