246 THE entomologist's record. 



Sub-family— ALEUEOPTERYGINiE. 



Two European species are known, namely, Helicoconis lutea, Wall., 

 and Aleurnpteriix loeiri, Klap., but neither have yet occurred in the 

 British Isles. 



1. Lower arm of cubitus ( ciio, ) in fovewing normal 



(fig. 12) ; nervule connecting radius and radial- 

 ramus in hindwing striking the latter on the 

 upper arm of the fork (r^+s, fig. 12) 



Helicoconis, Enderlein. 



2. Lower arm of cubitus ( ni-z ) in forewing strongly 



bent towards end (fig. 11) ; nervnle connecting- 

 radius and radial-ramus in hindwing striking the 

 stem {)■)■) of the latter well below the fork-point 

 (fig. 11) ... ... ... ... Aleuropteryx, Low. 



Notes on British Species. 

 1. Comventzia pmcifiniuix, Curtis. 



1834, Brit. Ent., pit. 528 : 1836, Steph., III., x., 117. 



Common throughout the summer (McLachlan). 



Evidently widely distributed. The following are some recent 

 northern records : — Quite common in the Cleveland district (Yorks.), 

 especially on holly (J. W. H. Harrison) ; Gibside, Co. Durham, and 

 Ovingham-on-Tyne, Northumberland (R.S.B.). Twenty-four examples 

 are in the Daleian collection. 



2. C(mwentzia piiieticola, Enderlein. 



1905, Ber. Westpi: bot.-zool. Yer., pp. 26-27, figs. 10 and 11. 

 Mr. Harrison brings this interesting insect forward in The Vascu- 

 liim, i., p. 56, 1915* recording it as very common and widely distributed 

 in the Cleveland area (Yorks.) on larch, and also records a pair from 

 county Durham. The insect is very variable, and it is possible that 

 the following, found on sallow, may prove to be a form of it, though 

 it differs in many points from Enderlein's description. The light 

 patches in the distal cells of forewing may have been overlooked in 

 pineticola — they are not present in examples of piiieticola I have 

 examined, but I have noticed variation in this direction in C. 

 psocifoDiris. 



3. Comcentzia cr)jptonci(ris, Bagnall, 



1915, f'nt. Mn. ]\Iai/., li., 192-3, June, and T/w ]'ascitli())i, i., pp. 

 22-24, figs. 1-3, June. 



Northumberland, Newcastle-upon-Tyne. Three examples found on 

 sallow, July, 1914. See above remarks. 



4. ('onio])tc'ri/,i- pijrpiiaeKs, Enderlein. 



1906, Zool. Jahrb., xxiii., Abt. f. Syst., p. 201, figs. 6, 86, 55, 58, 

 and 61. 



This species will probably be found in British collections mixed 

 with tineiformis. When fresh examples can be examined strong 

 differences will be found in the form of the last abdominal segment, 

 and in the structure of the genitalia in the S .
