Fabrician Types of Phryganida. 659 



them to be identical. But then there is the difficulty as to the 

 widely distant localities given as the habitat by the two authors. 

 As far as I can learn, there is no doubt that the type of Mr. 

 Walker's species was in a collection of insects sent from Natal by 

 Mr. Gueinzius, so the mistake must rest with Fabricius ; and I 

 may mention, that the only two species of Dipseudopsis at present 

 described are from the Old World, viz., D. Capensis, Walker, 

 from South Africa, and D. collaris, M'Lachlan, from China. 



The type specimen of P. notata does not agree with the above 

 description so far as the words " macula marginali fusca" are 

 concerned. One would imagine that Fabricius had before him 

 some species possessing a marked pterostigma, of which there is 

 certainly no sign either in his type or in that of Mr. Walker. 

 But as there is no evidence that the labels have been misplaced, 

 and no other insect in the Collection that we can reasonably sup- 

 pose to have a better right to the name, I think the specimen now 

 bearing that label must be considered as the type. 



In Dr. Hagen's work, P. notata is likewise placed in the genus 

 Neuronia (p, 252, 8), with the remark, " Is this N. semifasc'iata, 

 Say?" My notes sufficiently answer this question.
