THE CANADIAN ENTOMOLOGIST. 149: 
think is a rudimentary tongue, and on each side of it a smaller and more 
corneus projection, which I take to be the representatives of the maxillæ. 
Maxillary palpi three-jointed, the joints simple and of nearly equal 
length ; labial palpi small, simple, one (or two?) jointed (if two the basal. 
one is minute and indistinct.) Anterior tibia without spurs ; intermediate 
tibia with one short median, and one short and one long apical! spur ;. 
posterior tibia with two median spurs, one of them small, and two rather 
long apical spurs. 
The ciliæ, especially of the hind wings, are very long in both insects. 
The neuration is obsolete in Cyl/ene,; in Clymene it resembles closely that 
of Aydroptila tineoides Dalman, as figured by McLachlan in Zrans. Enr. 
Soc. Lond., Ser. 3, v. 5, plate 5, fig. 7. Indeed that of the forewings 1s- 
almost identical, whilst the hind wings differ somewhat both in shape and 
neuration. 
The specific description of C. aegerfasciella should be corrected by 
adding the statement that the hairs around the mouth are dark brown. 
By comparing the above account of these insects with Mclachlan’s 
account of the family Æyaroprilida and its two genera, Agraylea and 
Hydroptila, loc. cit., the differences to which I have alluded will be 
observed. 
BUCCULATRIX. 
This- genus is usually associated with Zzthocolletis and allied genera ; 
but the fact that it is an external feeder, except for a very brief period ; 
the absence of palpi and tongue, and the different neuration of the wings 
seem to me to remove it from that association. 
In addition to the points of structure just mentioned, a Bucculatrix 
has the basal joint of the antennae expanded, forming an eye-cap which 
almost conceals the eyes. The face is smooth and there is an erect tuft 
upon the vertex, and the antennae are nearly as long as the wings. 
A—Species having a brownish spot on the dorsal margin of the 
anterior wings. 
* Having an apical spot.

Unknown to me except by Dr. Clemens’ description. Wings ochreous 
with three silvery costal streaks.
