Plate C, figs. 1, 4, 10, 12 and 16). The maxillary palpi 

 have three segments extending forward nearly horizontally 

 and resting on the base of the labial palpi. They are densely 

 scaled, and at the outer end the scales form a triangle. 



Curtis figures the structural characters of what he calls 

 Tinea paleella Hiib. on Plate 109 of his "British Entomol- 

 ogy," together with Crambus radiellus Hiib., and represents 

 the maxillary palpus of paleella with four segments arising 

 from the side of the tongue. Felt, in his excellent work on 

 Crambus, gives a figure of the maxillary palpus of C. agita- 

 tellus, with four joints. 



The above studies were made on dry specimens, and a 

 fourth segment could not be found. Whether it is visible 

 in fresh specimens, I am not able to say. The maxillary 

 palpi in dry specimens of C. laqueatellus certainly do not 

 arise from the side of the base of the tongue, unless, in dry- 

 ing, the tissues about the mouth-parts have so shrunken as 

 to draw them far out on the sides, as shown on Plate A, fig. 

 3. Mr. Felt does not indicate the origin of the maxillary 

 palpi in his work. 



The prothorax is very small, and the upper side is divided 

 into two parts. Scudder has given the name of prothoracic 

 lobes to similar structures in the butterflies. The mesoscuta 

 are large, and extend far back on each side of the large meso- 

 scutellum. The metascuta are much smaller than the meso- 

 scuta, and are followed behind by the metascutellum. On the 

 forward edge of the metascutum there is an area (Plate A, 

 figs. 1 and 2) without scales or hairs, but covered with mi- 

 nute spines directed forward. This corresponds to a similar 

 spiny area on the under side of the fore wing. The abdomen 

 consists of eight segments. The genitalia of the male are 

 often retracted to such an extent that they are not visible 

 beyond the end of the eighth segment. No figures of these 

 organs are given here, as Mr. Felt has already given most 

 excellent figures of the genitalia of twenty-six different spe- 

 cies of Crambus. 



The legs (Plate A, figs. 5, 7 and 8) are of medium length 

 and size, and consist of the coxa, which is comparatively 

 long and stout ; the trochanter, which is of medium size ; 

 the femur, which is of medium size and length, the middle
