 Pityophthorus lateralis, n. sp. 



There is a short series of this species in the Cornell University Collection, 

 all from Key West, Florida. It is very closely allied to rhois and can be described 

 best by comparison. It is of the size, general shape and sculpture of rhois but 

 differs specifically as follows: The pronotum has the sides straight and parallel 

 on the hinder half and narrowly rounded on the front margin, with the marginal 

 serrations larger, becoming much longer on the middle line, and the perfectly 

 concentric asperities forming acute, serrate ridges; the punctures of the hinder 

 half distinctly sparser and smaller; the elytra have the punctures on the sides 

 very much smaller than those on the disc, with the lateral interspaces smooth 

 and shining, the sides parallel farther behind the middle, the sulcus of the 

 declivity deeper, the lateral convexities more strongly produced and more 

 compressed. 



The type is in the Cornell University Collection, and paratypes are placed 

 in the collection of the Entomological Branch. 



Pityophthorus confertus, n. sp. 



Description of the female. The length is 2 mm., the width about 

 one-third the length, 5:14; the elytra densely, rather coarsely, apparently 

 confusedly punctured, with the declivity sulcato-retuse and finely granulate on 

 the suture and lateral prominences. 



The head has the front subcircularly plano-concave, closely very finely 

 punctured and closely pubescent, the hairs bright-yellow and short except about 

 the margin of the pubescent area which bears a much longer fringe ; with a faint 

 trace of a median, longitudinal, less evidently punctured line, somewhat elevated 

 on the epistomal margin; the antennal club with the sutures deep, very broadly 

 arcuate, and strongly chitinized. 



The pronotum is as long as wide; with the hind margin very broadly rounded; 

 the hind angles rounded; the sides faintly arcuate, subparallel to beyond the 

 middle, then faintly constricted, and broadly rounded on the cephalic margin, 

 which is only very finely serrate, hardly noticeably so from above; the cephalic 

 half moderately subconcentrically asperate; rather closely and somewhat 

 roughly punctured behind, with the punctures very deep, rather coarse on the 

 disc, very much smaller on the sides, the smooth median space narrow, sub- 

 carinate near the summit; the ventral surface of the thorax finely punctured 

 behind. 



The elytra are nearly twice as long as wide, 9:5; with the sides subparallel 

 for three-fifths the length, narrowed behind, then strongly rounded at the hind 

 angles, with the declivity somewhat produced and the suture projecting beyond 

 the outline as viewed from above, not acuminate at the actual apex; the sutural 

 striae impressed, gradually more strongly behind, becoming deeply sulcate on 

 the declivity; the suture raised and nearly smooth on the disc; the other striae 

 not impressed except the last; the punctures rather coarse and very close, 

 apparently rather confused, but actually with very irregular strial and inter- 

 strial rows, the punctures of the latter as large and nearly as numerous as those 

 of the strial rows, more strongly confused near the suture and the side margins; 

 the pubescence short, erect and indistinct. The declivity is sulcato-retuse with 

 the punctures much smaller than on the disc, those of striae 1 an'd 2 nearly 

 obsolete; the sulcus moderately wide and deep, widest slightly behind the middle, 

 narrowed towards the apex, smooth and shining; the suture rather well 

 developed, finely uniseriately granulate-hairy; the second strise of punctures 

 minute, curving outward along the dorso-lateral margin of the sulcus; the 

 convexity somewhat compressed, finely, densely, and roughly punctured; the 

 third interspace with a row of about six small granules forming the margin of
