56 TAENIODERA. 



the name of » TricJiius" quadriline.atus. The original speci- 

 mens from Major Hardwicke's collection are in the British 

 Museum, and one of them, bearing Hope's label and evi- 

 dently the specimen which served as his type , is an exam- 

 ple of a common Indian species, in which the usual red 

 ground color of the elytra is entirely replaced by black ; 

 this has enabled me to determine without doubt as to which 

 species the name of quadrilineata should be applied. 



The second species is the quadrilineata G. & P. (Mon. 

 Get, p. 321, t, 63, f. 5), Dr. Schaum appears to have first 

 committed the error of regarding this species as identical 

 with quadrilineata Hope, with which it has ever since 

 been associated. It is evidently only by accident that Gory 

 adopted the same name (which he ascribes to Drapiez) for 

 his Javan species as had been used two years prior by 

 Hope for the allied Indian species. As it is therefore ne- 

 cessary to rename Gory's species, I have followed the usual 

 practice in such cases in proposing the name of Goryi 

 for it. 



The third species , scenica G. & P. , was considered by 

 Burmeister to be the male of quadrilineata G. & P., the 

 similar habitat, resemblance in color and the fact that 

 Gory's types of the two species chanced to be of opposite 

 sexes , are no doubt the reasons that he was led into this 

 error. I had long suspected that the dissimilarity in the 

 clypeus was not merely a sexual character, but we are in- 

 debted to Mr. Ritseraa for the first discovery and correc- 

 tion of this error (Notes Leyd. Mus. XII, p. 11). 



The fourth species is apparently undescribed. I have 

 therefore proposed a name and indicated wherein it differs 

 from quadrilineata. I have possessed specimens for some 

 years and have observed it in other collections under 

 that name. 



The following are the principal characters by which the 

 four species may be distinguished, after which I have given 

 further details of the points in which they differ, with 

 particulars of their localities as far as they are known to
