THE BRENTHID^ FROM JAVA. 183 



Observation. This species is labelled in some collections 

 with the names of Heteroplites unicolor Power and Diurus 

 unicolor Chevrolat, and it is the same insect which Lacor- 

 daire in his » Genera des Coléoptères" (Vol. VII, p. 471) says 

 to be an undescribed species of Heteroplites from Java, as I 

 find on the label of a specimen in my collection. This author in 

 the above-named work writes: »J'en connais trois" (species of 

 Heteroplites) »dont une seule [H. erythroderes Westw.), ori- 

 ginaire des iles Philippines, est decrite en ce moment. 

 Les deux autres soat de Java ou des Moluques" ; and in 

 the second note , speaking of the tails of the elytra , he 

 adds: »rune des deux espèces inédites les a aussi longues et 

 aussi grêles que Ie Diurus" ; and truly, in some specimens 

 of Cediocera tristis the tails are very long, as long as the 

 elytra. C. longicornis Pasc. too has long tails, but this 

 species is not from Java and seems to be a local form from 

 the Andaman islands. Thus I state that my C. tristis is 

 the species of Heteroplites mentioned but not described 

 by Lacordaire. According to Lacordaire's description of 

 Heteroplites^ no doubt Cediocera tristis must be included 

 in that genus , as well as C. longicornis Pasc. , which is 

 a very closely allied species. Nevertheless I refer the new 

 species to the genus Cediocei^a because it corresponds per- 

 fectly with the generic description given by Pascoe, and 

 I consider it to be a distinct genus because the characters 

 of Heteroplites ought to be modified for the reception of 

 some new species which , within a short time , will be 

 described by me; but at the time Cediocera was established 

 it was a doubtful genus, as Mr. Pascoe, in describing it in 

 the Annals and Magazine of Natural History, 1887, p. 20 

 compared it with Diurus and indicated its differential cha- 

 racters , without saying , however, by what characters the 

 new genus differs from Heteroplites. The differences between 

 Diurus and Heteroplites are the same as those between 

 Cediocera and Diurus, and I failed to find the distinctive 

 characters by which Cediocera was differentiated from He- 

 teroplites in the sense of Lacordaire.
