EUDELA. 



Pascoe, Ann. Mus. Civ. Genova, 1885, p. 237. 



This genus was referred to the Tychiides, by Pascoe, despite 

 its simple claws. There are, before me, two specimens sent by 

 Dr. Gestro as cotypes of E^idela rufescens, and with a label 

 "Borneo, Sarawak, 1865-66. Coll. G. Doria.""*^ They are 

 evidently sexes of one species, as the antennae are inserted at 

 about one-fourth from the apex of rostrum on one specimen (pre- 

 sumably the male), and not much nearer apex than base on the 

 other (presumably the female). But neither has dentate femora, 

 whereas, in the generic diagnosis, Pascoe said " Femora com- 

 pressa, dentata." As the specimens agree so well with the de- 

 scriptions in other respects, however, I wrote to Mr, Arrow, of 

 the British Museum : "I have two specimens sent by Dr. Gestro 

 as cotypes of Eudela rufescens; but they differ from the descrip- 

 tion in having the femora edentate. I would be glad, therefore, 

 if you would examine the type, and let me know if its femora are 

 really dentate. Also how is the prothorax carinate? My speci- 

 mens have the extreme outer margins acute, whereas Pascoe said 

 ' Prothorax .... ad latera carinatus,' and again, ' the sharp 

 elevated line or carina on each side of the prothorax.' " 



In reply, Mr. Arrow wrote : " I have examined the type of 

 Eudela rufescens. I find that Pascoe's description is quite 

 correct. All the femora are toothed, the four posterior ones very 

 bluntly, and the front ones acutely. Also, the prothorax is 

 flattened, and the lateral edges are sharp or carinate as in the 

 African genera Antliarhi7ius and Platymerus" 



It would appear, therefore, that the specimens sent by Dr. 

 Gestro are not E. rufescens^ but a species closely resembling it 



* The original locality, and one of the original collectors.
