THE CANADIAN ENTOMOLOGIST 



tionas to the identity oi Lonchocerus Dahlbom and Rileya Howard. His 

 statement that I had not consulted the European hterature is, of course, 

 uncalled for and absurd. I had not only familiarized myself with the 

 European descriptions, but had sent specimens to Dr. Mayr, who so ably 

 monographed the European Encyrtinae some years ago, and whose opinion 

 corroborated my own as to the novelty of this form. Mr. Ashmead's 

 comparison of Thomson's description with my own must have been most 

 hurried, as they differ so widely that I would advise him to retract his 

 expressed opinion for the sake of his entomological reputation. 



I tabulate here the differences which can be noted from comparison 

 of the two descriptions and my figure of Rileya. The quoted portions in 

 the Rileya column are from the description, and the unquoted portions 

 can be verified from the figure. Lonchocerus, by the way, is nothing but a 

 synomym of Mira, if Thomson is right in supposing that Dahlbom 

 founded the genus for Dalman's Encyrtus platycerus. Dahlbom's genera 

 in the Encyrtinre were described, however, without any indication of types. 



RILEYA HOWARD. 



" Face * * * gently rounded, and has 

 a strong, glistening, transverse, clean-cut 

 ridge just above the insertion of the an- 

 tenna;." 



Antennal club not jointed. 



Mesoscutum transverse, "highly po- 

 lished." 



" The mesoscutellum has a strong tuft of 

 erect, black hairs " at tip only. 



Wings not shortened ; when closed 

 reaching considerably beyond tip of 

 abdomen. 



" The stigmal vein is given off immedi- 

 ately at the juncture of the submarginal 

 with the costa." Consequently there is no 

 marginal vein. 



Abdomen flattened ovate, cutely pointed 

 behind, " highly polished." 



LONCHOCERUS DAHLBOM. 

 " Caput subtriangulare, vertice sat late, 

 lateribus tereti, medio subacute." 



" Clava 3-articulata." 



" Mesonoto [mesoscutum] haud trans- 

 verso, dense albo-sericeo." 



" Scutellum dense holocericeo - pubes- 

 cens." 



" Alse abbreviatse, Thorace vix super- 

 antes." 



" Stigmate [marginal vein] lineari, dis- 

 tincto." 



" Abdomen subglobosuni, dense albo- 

 pubescens." 



In conclusion, I wish to apologize for the slip (or misprint) in the use 

 of " 1887 " for " 1888." The change does not alter the relative order of 

 the events, and the date of reading the paper is unimportant.
