83. AGRILUS MALVASTEI, new species 



Figure 62 



Male. — Form robust, slightly flattened above, moderately shining, 

 uniformly green, with a distinct aureus or aeneous tinge, and each 

 elytron ornamented with a vague pubescent vitta. 



Head with the front rather narrow, nearly flat, slightly wider 

 at top than bottom, the lateral margins arcuately expanded above 

 the middle, and with a shallow groove extending from the occiput 

 to epistoma ; surface rather coarsely, irregular rugose, finely, sparsely 

 punctate, and sparsely clothed with semierect yellowish white hairs; 

 epistoma narrow between the antennae, and broadly, arcuately eniar- 

 ginate in front; antennae extending to middle of pronotum, serrate 

 from the fifth joint, and the outer joints about as wide as long; eyes 

 large, broadly oval, and about equally rounded above and beneath. 



Pronotum wider than long, narrower at base than apex, and widest 

 along apical half; sides nearly parallel or vaguely rounded from 

 apical angles to near base, where they are strongly sinuate, with 

 the posterior angles rectangular; when viewed from the side the 

 marginal and submarginal carinae are strongly sinuate, widely sepa- 

 rated anteriorly, and connected to each other behind the middle ; an- 

 terior margin moderately sinuate, with the median lobe broadly 

 rounded; base feebly, arcuately emarginate at middle of each ely- 

 tron, the median lobe broadly rounded, and subtruncate in front of 

 scutellum; disk strongly convex, with a vague median depression 

 anteriorly, a broad, oblique depression on each side along the lateral 

 margin, extending from apical fourth to base, and with rather dis- 

 tinct, obtuse prehumeral carinae; surface coarsely, densely scabrous, 

 sparsely, finely punctate, and sparsely clothed with long, recumbent, 

 whitish pubescence in the lateral depressions. Scutellum not dis- 

 tinctly carinate, but the surface more or less rugose, and finely re- 

 ticulate. 



Elytra slightly wider than pronotum at base, and about equal in 

 width at base and apical third; sides nearly parallel for a short 

 distance behind base, broadly, vaguely constricted in front of middle, 

 broadly arcuately rounded behind the middle, then obliquely nar- 

 rowed to the tips, which are separately, narrowly rounded, and 

 feebly serrulate; sides of abdomen narrowly exposed above; disk 

 slightly flattened, feebly, broadly depressed along the sutural mar- 

 gins, which are slightly elevated posteriorly, and with broad, shallow 

 basal depressions, surface coarsely, densely imbricate-punctate, 

 sparsely, uniformly clothed with short, recumbent, whitish hairs, 

 and each elytron ornamented with a feebly indicated vitta of simi- 

 larly colored hairs, extending from basal depression to apex.
