1. Descriptions o£ new Species of Beetles belonging to the 

 Family Erotylidce. By Henry S. Gorham, F.Z.S. 



[Eeeeived March 5, 1883.] 



(Plate XVIII.) 



Three years ago I had the opportunity of comparing with a portion 

 of my own collection of Erotylidce the one formed by the late 

 G. R. Crotch and now in the Museum of Natural History at Cam- 

 bridge. It is well known that my friend, with whom I spent many 

 pleasant hours in their examination, spared no time or trouble in 

 both acquiring and collating the types in those museums and private 

 coilectious which lie was able to reach. In the present paper it is 

 my object to describe some very conspicuous species which have 

 come into my own possession, i'roni various sources, some from the 

 private collection of Mr. G. R. Waterhouse, some from the collection 

 made in the Philippines by Herr C. Semper, and others from the 

 last collection brought by Mr. Buckley from Bolivia and Peru, 



I have commenced with the Encaustini, with which it appears to 

 me a linear arrangement should be headed. Their largely developed 

 and powerful form, which is at least as much specialized as the 

 genera placed before it by Lacordaire, seems to me of more im- 

 portance than a recondite structure of the maxillae. The gciius 

 Aulacochilus, again, is unnaturally separated by Lacordaire from 

 Episcapha, to vvhieh I have here placed it in proximity. The 

 present paper contains only an instalment of the new species known 

 to me ; the Langurini, Triplacini, and Erotylini proper must be left 

 for a future time.
