258 COLEOPTEKA, 



Group EUMOLI'IDAE. 



3665. Pilacolaspis rugiventris sp. nov. Pilacolaspis Sharp, Man. N.Z. 



Coleopt , p 1305. 



Oblong, moderately convex, nitid, rather thickly covered with 

 distinct pale-brassy pubescence; fuscous, slightly bronzed; palpi, 

 antennae, and legs testaceous. 



Head narrower than front of thorax, moderately finely and closely 

 punctate, more sparingly behind, where there is a linear longitudinal 

 impiession. l']yes subrotundate, prominent. Thorax about a third 

 broadei' than long, widest and rounded at the middle, somewhat sinuate 

 behind; posterior angles rectangular, the anterior a little depressed and 

 prominent; the basal and lateral margins more distinct than the frontal; 

 its surface a little uneven, being feebly bi-impressed near each side, 

 the punctation like that of the head, not coarse, but moderately close. 

 Scutellum quadrate, with a few fine punctures. Elytra nearly thrice 

 the length of the thorax, slightly broader than it is at the base, a little 

 broader near the hind thighs, with rounded apices; their punctation 

 irregular, hardly any coarser than that of the thorax, the sutural striae 

 obsolete near the base and only slightly impressed behind. 



Legs stout; tibiae a little dilated and excavate near the extremity; 

 claws appendiculate. 



Antennae stout, reaching backwards to the middle thighs, 2nd joint 

 subglobular, the following ones elongate, 3rd as long as 4th, the terminal 

 ones rather more slender. 



Underside fusco-testaceous, slightly aeneous, with distinct greyish 

 pubescence, finely transversely rugose, the penultimate and terminal 

 ventral segments punctate. 



Length, 4i-5 mm. ; breadth, 2-2^ mm. 



Methven. Three found by Mr. T. Hall during November and De- 

 cember, 1911. In one the sides of the thorax arc obtusely angulate; 

 this no doubt is the male. P. hutto/ii, 1 lOiJ, is the nearest species, but 

 it has grey pubescence, and the scutelhini is more triangular and closely 

 punctured. 



3666. Aphilon impressa sp. nov. ApMlon Sharp, Man. N.Z. Coleopt., 



p. 629. 



Convex, broadly oviform, glabrous, shining; nigro-aeneous, antennae 

 and legs testaceous. 



Head, including the convex eyes, almost as wide as front of thorax; 

 slightly bi-impressed between the eyes, and with a short, longitudinal, 

 median groove behind. Thorax twice as broad as long, widely but not 

 deeply emarginate in front, its sides finely margined, scarcely at all 

 rounded but gradually narrowed anteriorly, tlie base feebly bisinuate, 

 with rectangular l)ut not prominent angles; in front there is a short 

 gioove on the middle, and between it and each side a large foveiform 

 BomeAvhat transversal impression, near the base it is slightly bi-impressed; 

 its punctation is fine, shallow, and distant, near the base, however, there 

 are numerous coarser punctures. Scutellum distinct, smooth, and 

 snbcordate. Elytra of the same width, at the base, as the thorax, closely 

 applied thereto, thrice its length; their sides finely margined, only 

 modei'ately rounded, rather wider near the middle tlian elsewhere; they 

 are without any obviotis sculpture, but in certain liglits vague indica 

 tions of irregular striae may be detected.
