CORRESPONDENCE. 



UNIDENTIFIED BOMBYCIDS. 



Sir, — In regard to Mr. Smith's note on page 164 in Canadian Ento- 

 mologist for June, I would say that I am the authority for the reference 

 of Saligena persouata to Raphia f rater, and for the fact that now a 

 series of specimens of SpJiida obliquata are in Brit. Mus. Coll. under the 

 label of " Edema obliqua." I have not the Brit. Mus. lists before me, 

 but this series of apparently bred specimens of Sphida obliquata, which 

 I found on my second, were not in Brit. Mus. Coll. at my first visit, 

 when I examined the collection, with a specimen of the moth, for the ex- 

 press purpose of identifying the species. They could not have escaped 

 my notice. They must have been added subsequently to my visit and 

 description. On this first occasion I discovered, quite misplaced, the type 

 of the much more obscure species Arzama densa, Walk. ; without this 

 identification the name Arzama would have hardly been placed in our 

 catalogues. I recognized Sphida obliquata as allied to the type of 

 Arzama densa at a glance. I examined the Notodontidce carefully, making 

 several identifications, and the specimens now under Edema obliqua 

 were not then there. A reference to our original paper in Tr. Am. Ent. 

 Soc. Phil, will show that I examined the Notodontians carefully. The 

 probability is, that the species must remain as catalogued by me, viz. : 

 Sphida obliquata, G. & R., when the facts are all known. In cases where 

 specimens are simply stuck without type labels under printed labels in 

 Brit. Mus. Coll., they are not to be taken as Walker's type, when in any 

 way disagreeing with Walker's descriptions. A. R. Grote, Bremen.
