NOTE ON THE SET.E: OF THE LARV^: OF THYATIRID^:, 



AND A CORRECTION. 

 Recently I have examined the larvae of some European Thyatirid;e, 

 and find the setse arranged exactly as in our species. [See Proc. Boston 

 Soc. Nat. Hist., 1894, p. 399.] The supplementary seta behind iii. varies 

 a little in position, but is uniformly present. The species examined are 

 Habrosyne derasa, Thyatira batis, Bombycia oj-, B. diiplaris, Asphalia 

 ruficollis, 2ii\di A. fluctiiosa. A correction must be made in my descrip- 

 tion just referred to (pp. 400-401). The species there described in all 

 its stages as " Thyatira scripta " is really Bseudof/iyafira expultrix. 

 The following list may straighten out the matter : —  



Habrosyne scripta. 



1883. Thaxter, Papilio HI., 10. Describes egg and sixth stage. 

 Psetidothyatira cyinatophoroides. 



1863. Grote, Proc. Ent. Soc, Phil., H., 124, Sixth stage. 



1883. Thaxter, Papilio HI., 10. Sixth stage. 



1895. Dyar, Proc. Post. Soc. Nat. Hist., XXVI., 400. Egg, all 

 stages (as Thyatira scripta). 

 Ejithyatira pudens. 



1889. Dyar, Can. Ent., XXL, 209. Mature larva. 



Thus, the larvaj of only thirty-three per cent, of our species of 

 Thyatiridfe are known. This is a poor showing for such a small family. 

 Of the Notodontidae fully sixty-six per cent, are known,

A NEW GENUS AND SPECIES IN THE APHELININ.*:. 



BY L. O. HOWARD, WASHINGTON, D. C. 



I recently received from Mr. T. D, A. Cockerell, Las Cruces, New 

 Mexico, a minute parasite of a Ceroplastes on E^iphorbia hypericifolia 

 from the Red Hill district of Jamaica, which was transmitted to him by 

 Dr. M. Grabham. Both genus and species prove to be new, and are 

 printed separately, partly for the reason that my revision of the Aphelininae 

 of North America has recently been published and I do not expect to do 

 any extensive work on the subfamily again for some time, and partly for 

 the reason that Mr. Cockerell wishes to use the names in the Journal of 

 the Institute of Jamaica. The description follows :
