[LeConte. 



p. 330. in Rhyncliopliorini add : 



A specimen of the well-known Rhynchophorus palmarum was collected 

 by Mr. Hardy, in Southern California, west of San Diego, and kindly sent 

 to me by Dr. David Sharp. As groves of palm trees are known at several 

 places on the eastern slope of the Sierra in that region, it is not surprising 

 that they should be depredated on by this species, which is widely diffused 

 through the Antilles and tropical America. 



Quid? Rhynchophorus noxius Gyll. Sch iv, 821. Perhaps an im- 

 ported specimen of R. palmarum. 



p. 331. Add the three following new species of Sphenophorus ; the first 

 belongs to Horn's group IV ; the others to V ; Proc. Am. Phil. Soc. xiii, 

 412. 



Sphenophorus velutinus, n. sp. 



Elongate, brownish black, entirely opaque and velvety in lustre. Beak 

 shorter than the pro'thorax, curved, 'somewhat compressed, smooth ; an- 

 tennae inserted immediately in front of the eyes. Prothorax more than 

 one-half longer than wide, oval, strongly tubulate in front ; the elevations 

 are very vague and ill defined, the impressions are marked with shallow 

 punctures ; sides more densely and more deeply punctured ; dorsal line 

 narrow, slightly elevated, extending nearly to the base and apical constric- 

 tion . Elytra not longer than the prothorax, narrowed behind from near 

 the base ; striae very fine, marked w r ith a few distant small punctures ; two 

 outer striae with more numerous larger punctures ; interspaces flat, obsolete- 

 ly punctulate. Pygidium with a few large deep punctures, beneath 

 sparsely punctured. Front and middle tarsi with the third joint broadly 

 dilated, spongy each side beneath ; third joint of hind tarsi slightly dilated, 

 not wider than long. Length 11 mm.; .43 inch. 



One specimen, Florida. Very different from all others in our fauna. 



Sphenophorus variolosus, n. sp. 



Of the same general form as 8. arizonensis, black, somewhat shining ; 

 beak shorter than the prothorax, slightly curved, strongly punctured at, 

 base, nearly smooth at tip, which is moderately compressed. Antennae 

 inserted immediately in front of the eyes ; head finely and sparsely punc- 

 tured with a large frontal fovea prolonged anteriorly in a channel which 

 extends as far as the beginning of the narrow part of the beak. Prothorax; 

 oblong, longer than wide, sides strongly rounded in front, and tubulate at 

 the apex ; impressions and elevations very vague, indicated by the 

 presence of larger punctures in the places where the impressions should 

 be, and of finer punctures on the elevations ; there is a group of large 

 punctures just behind the tubular constriction, and behind these punctures 

 there is a smooth dorsal line extending nearly to the base. Elytra with 

 fine deeply impressed striae, along which are placed at irregular intervals 

 very large shallow pits, through which the striae run, producing a very 

 curious appearance ; interspaces finely sparsely punctulate, not elevated ; 

 the punctures of the outer striae are smaller and deeper ; those of the next
