"be referred to A, BB, but from the four species there 

 associated (as, in fact, from all others of the genus) it may 

 be readily distinguished by the bicoloured pronotum : on this 

 the black (or, at least, very dark-brown) markings are so 

 disposed that the castaneous parts form two large irregularly- 

 rounded patches. In some lights some of the hairs on the 

 front femora have a beautiful golden-rose gloss. The front 

 tarsi are of the same proportionate length as those of 

 froggatti. 



The specimen from Mr. Carter (labelled by the late 

 Rev. T. Blackburn "Not known to me") is considerably 

 paler than the others, with the pygidium obscurely reddish ; 

 it is also much less densely clothed (but this is probably due 

 to abrasion). 



Lepidiota darwini, Blackb. 



The type of this species was a female, but both sexes 

 were described by Blackburn. There are now before me nine 

 females, two of which were compared and agreed with the 

 type, and another is marked as a co-type. On all of them 

 the propygidium and abdomen are very densely clothed with 

 scales that are (either now or evidently once were) of a snowy 

 whiteness; on three of them the pygidium is moderately 

 ■clothed, but the scales are sparser and larger than on the 

 adjacent parts; on the others, however, the pygidium is 

 almost or entirely glabrous, and appears conspicuously black, 

 in striking contrast to the snowy scales near it ; it appears to 

 be a trifle longer than wide, but by actual measurement is 

 seen to be a trifle wider than long. 



There are also six males before me, two bearing Black- 

 burn's name labels and two others his number 2789 (in a 

 note-book recorded as darwini). At first glance these speci- 

 mens look strikingly different to the females, and I am by 

 no means satisfied that their identity is certain. They differ 

 in being smaller, paler (the colour gradually becoming still 

 paler posteriorly), prothorax more convex, with larger and 

 sparser punctures, without a shining median line (this being 

 distinct on all the females) ; elytra less regularly clothed and 

 with three or four fairly well-defined (although not 

 conspicuously elevated) glabrous lines on each (of these, on 

 the females there are scarcely any traces, or none at all, 

 although the type was said to "bear obscure indications of 

 three or four wide, scarcely-convex costae"). The pygidium 

 is more transverse than in the female (regularly clothed on 

 all six), the abdomen is smaller, and the elytra are less 

 dilated posteriorly, but these latter characters are certainly 

 sexual.
