much nearer the mid-dorsal line than the other subdorsals, and is 

 usually nearer to i than to its mate. Normally the prolegs have their 

 hooks arranged in a complete or broken ellipse; they are always 

 uniserial but often triordinal. Secondary hair occurs in Blastodacna, 

 a few subprimaries in Ethmia. The habits are various. 



The pupa is also characteristic and is obtect; usually the abdomen is 

 capable of dorso-ventral motion only, at three incisures. The body 

 is depressed. The epicranial suture is present. The prothorax is 

 hardly narrower on the mid-dorsal line than at the sides. The first 

 four abdominal segments are usually longer than the others. The 

 antenna 1 are usually adjacent for some distance on the midventral line. 



The Gelechioidea form the most homogeneous of the subordinate 

 groups of Microlepidoptera, and the largest of those groups. The 

 Thyrididae show some points of resemblance but will better be treated 

 with the Pyralidoidea. Besides these only the genera Scythris and 

 Euclemensia might perhaps be placed in this superfamily. 



Family 19. GECOPHORID^ 



(Depressariidae; Gelechiida3, in part) 



Moderately small moths, rather larger than the average size of the 

 Tineoidea. Head, typically, smoothly scaled, often somewhat rough. 

 Labial palpi long, upturned, reaching or surpassing the vertex, the 

 third joint nearly as long as the second, which is normally closely 

 scaled, or with a longitudinal divided tuft. Tongue developed, scaled. 

 Antennae most often without pecten, never with eye-cap ; both rows 

 of scales on the segments broadly interrupted in Semioscopis, Ethmia, 

 and a few other forms, as in the Macrolepidoptera. Hind tibia with 

 long loose hair, sometimes rather bristly, the bristles gathering into 

 tufts at the spurs. Tarsi nearly smooth, the spinules covered with 

 scales. Fore wing with R 4 and R- stalked, rarely united; the other 

 veins most often free ; never with more than one vein lost. Cu 2 aris- 

 ing well out toward the end of the cell, which is normal. 1st A 

 preserved toward margin, 2d A forked at base. 1st A very rarely 

 appearing like a fork near tip of 2d A, as in many Cosmopterygidae. 

 Hind wing with R separate from Sc but closely parallel on the basal 

 part of the cell, often connected to it by an oblique cross vein (RJ, 

 which rarely is as strong as the other veins (Endrosis; Ethmia, in 

 part). R and M x well separated at origin and parallel halfway to 

 margin, then divergent, but rarely more than twice as far apart at 

 margin as at origin; apex more or less rounded; the outer margin 

 not distinctly concave below the tip of R. M 3 usually connate or 

 stalked with Cu 1} M 2 usually from below middle of end of cell, stalked 

 with Cu in Triclonella, arising from cell nearer M t than M 3 in Ethmia
