are males. The venation agrees with the usual venation of the male T. con- 

 strictella. No indication of vein 7 was found in the hind wing; vein 6 reaches 

 the marg n considerably below the apex. 



Helice paUidochrella is found to be represented by females only. The 

 venation agrees with that of the female Theisoa constrictella; with slight dif- 

 erences indicating a more generalized condition, viz., in the forewing (Fig.24-f) 

 9 is separate from the stalk of 6, 7 and 8; in the hind wing (Fig. 24-g) 6+7 is 

 distinct to the base, but its course is exactly that of this vein in T. constrictella 

 female. 



My conclusion is that Theisoa permolestella is the male of Helice paUido- 

 chrella. In the genus Helice we have an extremely specialized Gelcchiid genus, 

 of which the female of one species, in venation the least specialized, has alone 

 retained the characteristic Gelbchiid shape of the hind wing. Another .factor 

 which argues against the retention of the genus Theisoa as a Cosmopterygid 

 genus, is that the costa of the hind wing does not show^ a degree of modification 

 in outline corresponding to the specialization in venation. 



The supposed specific dift'erences separating Theisoa permolestella from 

 Helice paUidochrella, are not confined to either, but are shown in individuals of 

 both. Late summer specimens of males (supposed T. permolestella) and females 

 {H. paUidochrella) show a dark tornal spot opposite the costal spot at the apical 

 third, which is more or less distinct, sometinies as large as the costal spot. 



The synonymy of the genera and species under discussion will, "therefore, 

 stand as follows:

Sulcacis lengi Dury. 



This species, which was described by Dury in 1917 (Syn. of Col., Fam. 

 Cisidae (Cioida-) of Amer. N. of Mex.-Jour. Cin. Soc. Nat. His., Vol. XXII, 

 No. 2, p. 20) from Vermont and Cincinnati specimens, has recently been found 

 in New Jersey breeding in the following fungi,** — Lenzites betulina L., Polyporus 

 versicolor L., Polyporus gilvus Sch., and Polyporus hirsutus Wul., all of which 

 occur on dead wood of deciduous trees. It was most abundant in Polyporus 

 versicolor at Monmouth Junction, N.J., and occurred only sparingly in Polyporus 

 hirsutus. 



Hibernation appears to take place in both larval and adu't stages, as both 

 of these forms were found on March 1 , but no pupa?. By keeping the infested
