veins, one above and parallel to the median vein, the other, above and 

 parallel to the discal branch. 



Fore wings elongate-lanceolate. The dlscoidal cell is obliquely placed 

 in the wing, its lower angle approaching very near the dorsal margin 

 of the wing. The subcostal vein is arched, and gives off a long, oblique, 

 marginal branch from behind the middle of the wing, one at the supe- 

 rior angle of the cell and one intermediate. A very short and indis- 

 tinct vein closes the cell posteriorly, and two indistinct apical veins 

 succeed the third subcosto-marginal branch, one of which is delivered 

 to the tip and the other to the costa behind the tip. 



The median vein is 3-branched, the two superior branches sometimes 

 from a common base and the posterior branch extremely short and in- 

 distinct; thence the median, runs obliquely and direct to the base. 

 The submedian is indistinctly forked at its base. 



Head smooth, without ocelli. Antenna} rather more than one-half 

 as long as fore wings, setaceous, joints thickly set, without hairs; the 

 basal joint, short. Labial palpi moderately long, recurved, acute ; 

 second joint compressed, subclavate. Tongue moderate, clothed with 

 scales. 



Batrachedra salicipomonella. — Fore wings fuscous, with a rather broad whit- 

 ish stripe, freely dusted with fuscous, running through the middle of the wing, 

 from the base and along the apical margin to the tip. Near the basal third of 

 the wing on thedorsal edgeof the whitish stripe is an elongate, blackish-brown 

 spot, and from the middle of the wing towards the tip. it is edged on its costal 

 side by a blackish-brown line which contains sometimes a spot of the same hue. 

 The apical portion of the stripe is more freely dusted with fuscous than the 

 other portions. Cilia fuscous. Hind wings fuscous, cilia paler. 



Antennae dark fuscous, without white annulations, except near the tip. Head 

 fuscous above, face white. Labial palpi dark fuscous ; second joint, with a 

 white ring at the extreme tip, sometimes white at the base, with a broad fus- 

 cous ring near the tip ; terminal joint fuscous, with a more or less distinct 

 whitish central ring and the extreme tip whitish. 



This is a very interesting -'micro." not only in consequence of the 

 specific resemblance it bears to the European Batrachedra prsean- 

 gusta, but of the discovery of its larva by one of our most gifted and 

 promising entomologists, Mr. Benj. I). Walsh of Rock Island, 111. 



In the note which accompanied the perfect insects, Mr. Walsh 

 writes: "I enclose herewith several specimens of a moth, bred from 

 the Tenthredinidous gall Salic is pomum Walsh MS., and a single one 

 from the Cecidomyiadous gall S. rhodoides Walsh. This is the iusect 

 that 1 think I mentioned to you as being very prettily marked in the 

 larva state, each segment having a broad, black band and the ground 

 color beimi' whitish. I had a single one come out last summer, but
