114 Phytoplutga Malayana. 



punctato ; elytris oblongis, infra basin et intra callum hume- 

 rale excavatis, subtenuiter seriatim punctatis, striis indistincle 

 bifariam dispositis ; antennis clava modice dilatata, nigra ; 

 frontis margine antico obtuse angulato, medio in lobum ob- 

 tusiim pauUo producto. 



Mas. — Tibiis intermediis extus leviter sinuatis. 



Long. 4 lin. 



Hab, Waigiou. 



Head very distantly punctured, front impressed with the usual 

 longitudinal groove; anterior border separated from the encarpae 

 and epistome by a deep sutural groove, very obtusely angled, ob- 

 soletely excavated on either side, the apex produced into an obtuse 

 lobe ; epistome scarcely longer than broad, campanulifonn ; en- 

 carpae broadly cultriform, their surface smooth, nearly plane, not 

 thickened above ; antennae two-thirds the length of the body, five 

 upper joints moderately dilated, nearly equal in width, black. 

 Thorax slightly broader than long, sides rounded and converging 

 from base to apex, more quickly rounded in front, nearly parallel 

 at the base, hinder angles armed with a short tooth ; above sub- 

 cylindrical, sides in front broadly and strongly deflexed ; surface 

 deeply but remotely punctured. Elytra oblong, convex, not very 

 strongly punctured, punctures irregularly arranged in longitudinal 

 rows, which indistinctly approximate in pairs ; below the basilar 

 space is a transverse excavation, which, commencing a short 

 distance from the suture, terminates just below and within the 

 humeral callus, its outer half much more deeply excavated than 

 the inner portion ; humeral callus moderately thickened, bounded 

 within by a longitudinal depression, which unites at its lower 

 end with the transverse excavation. 



Cori/nodes propinquus and the two preceding species, mulabilis 

 and fulgurans, are very closely allied, and I formerly considered 

 them as mere varieties of one species. C. mulabilis and fulgurans 

 may be known from each other by tlie difference in colour and 

 by the different form of the anterior border of the front ; in C, 

 fulgurans also the punctuation of the elytra is finer, and the inter- 

 space between each double row of punctures broader ; in C. 

 propinquus the form of the anterior edge of the front differs from 

 that of either of the two preceding species, and the rows of punc- 

 tures on the elytra are less distinctly arranged in pairs.
