PSYCHIDAE 



Apterona fragilis sp. nov. (PI. Ill, Fig. 21). 



$ . Antennae strongly bipectinate ; head and thorax sparsely clothed with 

 long whitish hair; wings semitransparent, blackish, finely clothed with long 

 black hair; abdomen scarcely exceeding hind wings. Expanse 11 mm. 



Habitat : Redington, Ariz. ; Paradise, Ariz. 2 $ . Types, Coll. Barnes. 



The ' reference to this genus as defined by Spuler (Schmett. 

 Europ. II, 180) would seem to be indicated by the presence of 7 

 veins on secondaries and 10 veins on primaries; on secondaries veins 

 4 and 5 are either connate or slightly stalked, 8 is connected with 7 

 by a cross bar; on primaries vein 1 a is obsolete and the other veins 

 are well separated, almost equidistant, with the exception of 4 and 5 

 which are rather closer to each other at the point of origin. 



COSSIDAE 



Acossus connectus sp. nov. (PI. I, Fig. 5). 



Thorax roughly scaled, pale brownish, tinged with white at base of meta- 

 thoracic tufts; primaries with the basal half light smoky brown, the outer half 

 paler and tinged with silvery white ; numerous deep black transverse streaks are 

 present besides two rather prominent postmedian irregular lines, connected to- 

 gether in the fold by a black streak, diverging towards costa, the outer one 

 forking near the apex of the wing ; along the outer margin are slight black reticu- 

 lations. Secondaries paler with only traces of reticulation. Beneath smoky 

 brown with faint reticulation. Expanse 30 mm. 



Habitat: San Benito, Texas (April 24-30). 1$. Type, Coll. Barnes. 



The species at first sight greatly resembles Fania nanus Stkr. 

 but apart from a somewhat different arrangement of the lines and 

 reticulations differs in the venation of the secondaries in which veins 

 6 and 7 are well stalked and veins 4 and 5 connate from the end of 

 the 'cellula intrusa' which is only faintly developed owing to the 

 partial obsolescence of the discocellular vein. We place the species 

 provisionally in Acossus, until more material is obtainable, as it seems 

 to show considerable affinity to tmdosus Lint. ; it is however very much 

 smaller than this species.
