on capis, grote. 

 Dear Sir, — 



Mr. Grote's reply to my remarks on Capis contains a statement which 

 requires correction. He says : " Every student ought to know that in the 

 Deltoids the eyes are always naked, the tibise unarmed." The latter part 

 of the sentence is correct, but as a very fair proportion of the Deltoidcn 

 have lashed eyes — Mr. Grote, himself, having described three genera with 

 that character — the remainder of it is rather new and surprising, and con- 

 tains information which all students are excusable for not having previously 

 known. Generic descriptions should always be complete. Capis is said 

 to be like Sisyrhypena ; that genus is described as Crambiform. Before 

 it is possible to know what Capis is like, we must go through Sisyrhypena, 

 hunt up what Crambiform is, and graft on that the difference between 

 Capis and Sisyrhypena ! I do not consider my " Remarks on Capis " 

 answered by Mr. Grote's reply. I am obliged to Mr. Grote for his offers 

 of assistance. John B. Smith.
