276 ON MEL0L0NTHINE BEETLES OF THE GENUS ECTINOHOPLIA. 



magno ; elytris postice separatim rot'unclatis, ad suturse finem 

 haud fasciculatis ; pedibus gracilibus, posticorum ungne fisso. 



Long. 7 # 5 mm. ; lat. max. 3'5 mm. 



Hah. Tonkin : Chapa (R. Vitalis de Salvaza — June). 



I refer this species to Ectinohoplia because the propygidium is 

 almost entirely uncovered by the elytra, but the latter are without 

 the usual tuft of bristles at the sutural angles. The nebulous 

 pattern of the elytra is unlike that of any species of Ectinohoplia 

 except E. inclica Moser, but is of a type common to many species 

 of Hoplia (e.g. H. elegantula White, aurantiaca Wat., aurotincta 

 Fairm., etc.). The ground-colour is an ochreous yellow, some- 

 times with a tinge of green, and there are vague markings of a 

 fawn or pale chocolate colour, consisting of a transverse patch 

 on each elytron behind the middle and a paler, less-defined, 

 and narrower arcuate patch before the middle. The scutellum, 

 the outer margins, and a patch at the end of the suture are 

 also generally darker than the general surface. The lower 

 surface is densely clothed with yellow scales, and those of the legs 

 and the clypeus and anterior part of the head are of a pale golden 

 colour. The species is elongate, with the pronotum distinctly 

 transverse but narrower than the elytra, its sides strongly con- 

 tracted before and behind, the angles well-marked, the front 

 angles acute, the hind obtuse, and the base lobed in the middle. 

 The scutellum is large and the elytra are little flattened. The three 

 teeth of the front tibia are strong and sharp, and not placed close 

 together. The claw of the hind tarsus is cleft. In the female 

 the scales of the median anterior part of the pronotum are 

 metallic, a,s well as the whole of those upon the head.
