wings variable, most frequently originating beyond the transverse 

 median nervure, more rarely interstitial . .Family XXV., Sphegidse. 

 Clypeus posteriorly usually carinate or produced between the insertion 

 of the antennae so that its basal margin is beyond a line drawn 

 from their base ; anteriorly it is often rostriform carinate, or at 

 least more or less produced medially ; metathorax usually long, 

 abruptly truncate posteriorly with the angles acute or toothed, 

 although sometimes the angles are rounded ; pronotum rather long, 

 conically produced Family XXVI., Ampulicidae. 



CORRESPONDENCE. 



Spilosoma congrua, Walk. 



Sir, — As I understand the Rev. Mr. Fyles's recent article on 

 Spilosoma congrua^ it is contended (i) that S. congrua, of Walker, is the 

 same as ^. antigone, Strecker, and (2) that cunea, Drury, is also antigone, 

 not textor, Harris. 



To the former proposition I am inclined to assent on the following 

 grounds : . . 



1. Grote, who made the first examination of Walker's specimens, 

 recognized in them a distinct species. 



2. Walker knew cunea, Dru., and well separated it from his congrua 

 in these words (Cat. Brit. Mus., III., 667): 



A. Alee anticai alba;. 



B. Abdomen non maculatum. 



a. Alai sat angusta? cunea, Drury. 



b. AIk latas congrua, Walker. 



3. Prof. Smith's statement (Ent. Amer., V., 119), that Walker's 

 description oi congrua does not apply to aniigotie was doubtless due to 

 his not having before him any specimens of Mr. Fyles's variety "f " 



We may then return to the old synonymy of the species : 



S. congrua. Walk. 

 antigofie, Strk. 

 The larva has been described in the following places : 

 1870. Saunders, Can. Ent., III., 36 (as H. cunea).
