28 On a few Melohnthine Goleoptera. 



This is a species closely related to the very abundant 

 L. stigma, F., of the Malay Peninsula and Java, which is 

 apparently not found in Borneo. The females of that species 

 strongly resemble the present insect, but the latter can be at 

 once distinguished by the sharply defined yellow or reddish 

 lateral borders of the elytra, almost denuded of scales. The 

 border occupies about one-eighth of the width of the elytron, 

 is paler than the remaining surface, smooth and shining, 

 and bears only a few minute scales, whereas the remaining 

 surface of the body is closely covered with scales, replaced by 

 short, close-lying yellowish hairs upon the coxae and the sides 

 of the metasternum. The scales of the upper surface are 

 generally pure white, the elytra each showing three more or 

 less distinct longitudinal lines of scales still more closely 

 crowded than the rest. Upon the head, the sides of the pro- 

 notum, and the lower surface of the body the scales are more 

 yellowish. 



The two sexes, unlike those of L. stigma, are alike in colour, 

 but the female is distinctly larger than the male, its front tibice 

 are stouter and bear three well-developed teeth instead of two, 

 and the hind tibise are dilated at the end and their spurs 

 broad and spatuliform (much more so than in L. stigma), the 

 extremities dilated, rounded, and translucent. 



L. munda, Sharp, has similar bare lateral margins to the 

 elytra, but is a smaller insect, more tapering in front, and 

 clothed with yellow scales. 



The Dalla Torre Catalogue is entirely wrong in identifying 

 the European Polyphylla alba of Pallas and Olivier with the 

 female of L. stigma (Melolontha alba, F.). 



Lencopholis diffinis, Sharp, and lateralis, Brenske, are, I 

 believe, synonyms of L. nummicudens, Newm. The incon- 

 spicuous row of hairs upon the median line of the pronotinn 

 seems to occur only in the female (the sex described by 

 Brenske), and is present in one of the two original specimens 

 of Newman. Sharp's two specimens are presumably both 

 females, but very much abraded, so that the clothing could 

 not be described. Brenske appears to have believed Penang 

 to be in Sumatra (Stett. Ent. Zeit. 1896, p. 189). 



Another related insect re-named in error is Eucirrus mellyi, 

 Guer., which, as I have already recorded, is a Malayan form, 

 not Ceylonese. The elongate palpi, which Brenske believed 

 to characterize a second species (E. elegans), is a feature of 

 the male of E. mellyi. 



Another redundant name for a sexual form may be noted 

 here. Moser has described as Hoplia thoracica an insect
