262 COLEOPTERA 



I have not seen Hope's description. Mr. White states that the 

 thorax is smooth, and the head unspotted ! 



The following are synonyms : Melolontha suturalis (Fabr. Ent. 

 Syst. ii., 161, Oliv.) ; Micronyx chlorophyllus (Boisd. Voy. Astrol. ii., 

 189) ; Rutele chlorophylls (Boisd., I.e., Atlas.) 



Pyronota. 



Hope; Lacord. Hist, des Ins. Coleop., Tom. \\\., p. 224. 



Mentum slightly convex, rounded laterally at the base, its ligular 

 part a little narrower, widened and slightly hollowed in front. Jaws 

 very robust, their external lobe furnished with five or six teeth. Last 

 joint of all the palpi sub-cylindrical, a little arched, and rounded at the 

 end. Labrum horizontal, scarcely extending beyond the ciypeus, 

 widely and rather strongly emarginated. Ciypeus transversely quadrate, 

 separated from the forehead by an angular furrow, margined, sinuated 

 in front. Eyes moderate. Antenna nine-jointed, the first clavate, 

 second also thick, three to five elongated, sub-equal, sixth very short, the 

 three last forming an oblong club among the males, short in the females. 

 Prothorax transversal, slightly narrowed in front, bisinuated at its base, 

 with pointed posterior angles, it is closely applied to the elytra and 

 rather wider than them. Scutellum curvilinearly triangular. Elytra 

 oblong, striate, partly covering the pygidium. Legs rather long, a little 

 robust, anterior tibia bidentate in the male, tridentate in the female, 

 sometimes bidentate in both sexes, the four posterior spinose ; tarsi 

 slender, longer than the tibiae, their claws slender, having between each, 

 at their base, two divergent membraneous plates. Posterior coxa spinose 

 on the inner side. Pygidium sub-horizontal, curvilinearly triangular. 

 The projecting sternal process very long, conical and rather acute. 



NOTE. Lacordaire accepts Boisduval's name, and gives the above 

 cited description ; but Boisduval did not characterize the genus, he 

 merely made some remarks (Voy. de r Astrolabe, ii., 213, 1835). Blan- 

 chard established the genus Colymbomorpha for an insect from Swan 

 River (lineata, Bl.), which cannot be separated generically from P. 

 f estiva and P. refulgent (Cat. de la Coll. Ent. du Mus. d'Hist. Nat. 

 Paris, 98, 1850). 



Hope established his genus Calonota upon the Melolontha festiva 

 (Pyronota) of Fabricius, giving characters as far as he was able from the 

 only mutilated specimen he possessed (Coleop. Manual, i., 107, 1837). 



It appears therefore that Hope really first characterized the genus, 

 and I have given his name as the author. This has also been done in 

 Gemminger and Harold's catalogue. 



For the above information I am indebted to Mr. E. W. lanson, 

 London.
