596 Mr. G. J. Arrow on the genus 



that originally described by Dr. Leconte, for besides the 

 want of* agreement in habitat there is a discrepancy in 

 the characters mentioned by the two authors, especially 

 those peculiar to the male. 



H. denticulata, Smith, is identical with H. dubia, F., a 

 label marked N. H. borne by the type specimen evidently 

 having been interpreted by Smith as signifying " New 

 Holland." There are other specimens, however, in the 

 Museum, obviously belonging to the same collection and 

 which have certainly come from the United States. 



H. serrata (Dendwphagus serratus), Smith, a Philippine 

 species, has been redescribed by M. Grouvelle as H. con- 

 formis; and the Ceylon representative of the genus has 

 also been twice described, first by Candeze as Brontes 

 serricollis and two years later by Motschulsky as B. ceylon- 

 icus. The later description contains a strange mistake, 

 the dimensions being given as length -§• line, and breadth 

 § line. Such a proportion for any insect of Brontes-type, 

 described moreover as " elongatus" is evidently wrong. 

 The breadth stated is that of H. serricollis, and the other 

 figures are no doubt the result of a slip. 



Brontes lucius and nigricans, of Pascoe, have been pro- 

 nounced by OllifT, with some hesitation, to be one species. 

 A comparison of the types leaves no doubt whatever upon 

 this point. Erichson's description of Brontes australis 

 also applies exactly to this species, and although OllifT has 

 separated them in his catalogue of the Cacujidae of 

 Australia I have no doubt of their identity. It is notice- 

 able that Pascoe has compared H. lucia and nigricans with 

 the dissimilar H. militaris, Erichs., but omitted any com- 

 parison with H. australis, Erichs., although described 

 upon the same page. H. lucia appears to be common in 

 Tasmania, and it appears to me most probable that OllifT 

 has given Erichson's name to an undescribed Tasmanian 

 species, possibly that to which I have given the name of 

 H. bicolor on a later page. Erichson has applied the 

 name australis to two species, placing one in Dendrophagus 

 and one in Brontes. I have therefore used the name lucia 

 for the latter, retaining Erichson's name for the other. 



Hyliota atrata, Reitt., being the same as H. spinicollis, 

 Guer., as I have been able to ascertain from a typical 

 specimen in M. Rene Oberthtir's collection, the Madagas- 

 car species given the same name subsequently by M. 

 Grouvelle may be allowed perhaps to retain it.
