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 maxillae. 

 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 cilios, especially of the hind wings, are very long in both insects. 

 The neuration is obsolete in Cyllene; in Clymene it resembles closely that 

 of Hydroptila tincoides Dalman, as figured by McLachlan in Trans. Ent.. 

 Soc. Lend., Ser. j, v. 5, plate j, fig. 7. Indeed that of the forewings is 

 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 Hydroptilida and its two genera, Agraylea and 

 Hydroptila, toe. cit., the differences to which I have alluded will be 

 observed. 



BUCCULATRIX. 



This genus is usually associated with Lithocollrtis 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 winars. 



* Having an apical spot.

Unknown to me except by Dr. Clemens' description. Wings ochreous 

 with three silvery costal streaks.
