benefit of those who have not given special stud}^ to the Microlepidop- 

 tera it should be said that of well-known moths this species bears a 

 superficial resemblance to the genus Ephestia, which includes the Medi- 

 terranean flour moth and the still commoner though less troublesome 

 dried-currant moth. It has, however, a more robust bodjr; both pairs 

 of wings are darker, the hinder ones more noticeably so and the pat- 

 tern of the fore-wings is less distinct. The head is considerably larger 

 and the male antennae alone, as previously remarked, will serve to 

 distinguish the genus from any other of the Phycitina?. A female 

 moth is shown twice natural size at a, the structure of the male antenna 

 at Z>, fig. 1. The moth is subject to some variation as regards the 

 markings on the wings, which are sometimes more suffused than in 

 the specimen figured. 



The wing expanse is about seven-eighths of an inch (21 mm. in the 

 male; 23 mm. in the female). . 



TECHNICAL DIAGNOSIS OF THE GENUS MONOPTILOTA HULST. 



Palpi ascending, second article heavy, third short; maxillary palpi small; front 

 broad, flattened; ocelli not discernible in imdenuded specimens; antennae of $ , first 



Fig. 1. — MoTwptilota nubileUa: a, female moth: b, antenna of male: c, gall of larva; d, young larva; 

 e, first abdominal segment of same from side;./", mature larva; g, cocoon — all about twice natural 

 size, except b and e which are much magnified (original) . 



segment much lengthened, swollen, followed by a decided, rather lengthened bend, 

 hollowed on the inside into a deep furrow, or pocket, its entire length, the edges of 

 the furrow scaled, becoming tufted on posterior edges outwardly; b?yond sinus 

 filiform ; from beyond basal joint the antennae are unipectinate, the pectinations one on 

 each segment, filiform, being longest just beyond sinus and these five or six times 

 the diameter of the stem, each armed with straight parallel hairs on each side; end 

 segments ciliate. Antennas of £ filiform, ciliate; thorax and abdomen rather stout, 

 the genital armature of $ prominent. Fore wings rather elongate, subtriangular, 

 11 veins, 4 and 5 separate, 6 from cell near angle, 8 on 7, 9 and 10 from cell. Hind 

 wings broad, 8 veins, 2 near angle, 3 from angle separate from 4, 4 and 5 stemmed 

 half their length, 6 separate from 7; cell very short, not more than one-fourth wing 

 length. Legs as usual in the group, rather heavy. (Hulst.)
