430 Mr. T. V. WoUaston on Coleoptet^ous Insects from China, 



XLIII. — Descriptions of two Coleopterous Insects from the North 

 of China. By T. Vernon Wollaston, M.A., F.L.S. 



The two insects the descriptions of which I have given below 

 were collected by Mr. Fortune in the north of China ; and I 

 propose to dedicate them to my learned and excellent friend the 

 Barao do Castello de Paiva, Professor of Botany in the Academic 

 Polytechnique of Oporto, and a member of many scientific socie- 

 ties both in Portugal and France, whose botanical researches 

 in Madeira and the Canary Islands have been so long and so 

 justly appreciated by the leading naturahsts of his own country. 



Fam. MelolcmthidaB. 



Genus Hoplia, Illiger. 



Hoplia Paivcs, 



II. subovata, supra depressa nigra, prothoracis limbo, linea centrali 

 lineaque breviore intermedia necnon elytrorum sutura fasciisque 

 tribus transversis squamis subviridescenti-albido-luteis dense vesti- 

 tis, antennis pedibusque rufo-ferrugineis plus minus vestitis, ilia- 

 rum clava obscuriore. 



Variat corpore (supra et infra) squamis paUidis vestito, lineis fasciis- 

 que plus minus suffusis. 



Long. Corp. lin. 3|-4. 



H. subovate, beneath exceedingly convex and densely clothed 

 with yellowish-white scales, having an iridescent or greenish tinge; 

 above much depressed, black ; but more or less beautifully varie- 

 gated with paler scales of the same colour as those below. Pro- 

 thorax with the margins, a central line, and a shorter interme- 

 diate one on either side (connected with the anterior margin, 

 but not reaching to the hinder one)] covered with pale scales. 

 Elytra with the suture and three transverse fasciae (sometimes 

 distinct and sometimes interrupted) likewise pale. Limbs rufo- 

 ferruginous, and more or less clothed with paler scales; the 

 cluh of the antenna darker. 



[In some specimens the entire upper surface appears to be 

 almost clothed with paler scales, leaving the bands and fasciae 

 exceedingly obscure; nevertheless even in examples such as 

 these their form is more or less traceable.] 



Fam. Erotylidae.
