1044 COLEOPTERA 



little from one another ; ninth and tenth large, about equal ; 

 eleventh larger than tenth, obliquely pointed. Thorax half the 

 width of the elytra, longer than broad, convex, medially dilated, 

 without impressions. Elytra as long as thorax, much narrowed 

 towards the base ; with well-marked sutural striae, deepest in front, 

 but without other definite sculpture. Hind-body broad, widely 

 margined at the sides, basal segment ample, smooth. Legs elongate, 

 posterior tibiae straight inwardly, but, externally, curved and ex- 

 panded near the extremity. 



Underside of basal ventral segment densely fringed with bright- 

 yellow pubescence, as in P. delicatus. 



Allied to No. 1153, but at once differentiated by its smaller size 

 and differently-formed maxillary palpi, which in this species are 

 much shorter than the antennae; the second and fourth joints are 

 considerably bent, and the latter is terminated by the usually 

 moderate, cleft club. The thorax, though convex, does not exhibit 

 the longitudinally-ridged appearance of P. dulcis. P. ciecns and P. 

 delicatus are abundantly distinct.

Howick. One individual only. 



1868. P. meliusculus, n-s. Shining, chestnut-red, palpi and 

 tarsi yellowish ; sparsely clothed with short, slender yellow hairs. 



Head ovate, the channel between the elongate, pubescent 

 frontal elevations moderately broad and deep ; between the eyes are 

 two rounded foveae, but, the frontal channel being interposed, the 

 interocular space seems to consist of one large depression ; . the 

 hinder portion is convex, with an indistinct median groove. Thorax 

 elongate, narrow, more narrowed in front than behind, with a 

 curved impression near the base, ending in a small fovea near each 

 side. Elytra, behind, nearly twice as broad as thorax, much nar- 

 rowed and curved towards the base ; the sutural region depressed, 

 and the striae there well marked, the discoidal stria foveiform at the 

 base but quite obliterated behind ; each elytron with three rows of 

 fine hairs, the apices ciliated. Hind-body with very few hairs ; the 

 basal segment large and broadly margined, second and third mode- 

 rately short. Legs elongate; femora clavate, so that there appears 

 to be a sort of constriction near the extremity of each ; tibiae some- 

 what expanded and curved towards the apex ; tarsi with the second 

 joint rather thick. Antenna longer than the head and thorax, 

 ninth joint rather longer than but not quite as broad as the tenth. 

 Palpi (maxillary) elongate ; fourth joint slender, much curved, its 

 clavate portion cleft to the base and less than half the entire length. 



Allied to P. pauper.
