yEgeria gallivora, West. — In May last I obtained from a globular 

 excrescence on an oak twig three ^gerians — one male and two females. 

 They were at first taken to be JEgeria hospes, Walsh, until a careful 

 comparison was made with the original description of that species in 

 vol. vi., p. 270, of the Proceedings of the Entomological Society of 

 Philadelphia, when I found good evidence that the moths were not of 

 that species. The following characters seem to afford sufficient grounds 

 for this conclusion : — i. They were larger, expanse .75 inch (Hospes .57 

 inch ) ; 2. there is a well-marked black band at tip of hind tibiae, in the 

 female as wide as half the length of the joint, or the whole space distal 

 of the middle spurs (Hospes has the tibiae tipped with blackish only) ; 3. 

 the second abdominal band of female is broad and the yellow ventral 

 patch much longer and more clearly defined than in the male (according to 

 Walsh, this band is not broad and the spot is only half as long as in the 

 male) ; 4. the expanse of Hospes female is .50 inch, of these .75 inch; 5. 

 and again, these have a yellow collar and the first joint of the antennae 

 maculate in both sexes, whilst the female Hospes has the first antenna 1 

 Joint immaculate (Walshj. 



Are these moths Westwood's T7-ochiliiiin gallivora ? His description 

 is inadequate, and without a comparison with the type there must always 

 remain some uncertainty. Nevertheless, I refer my specimens to that 

 species for the following reasons : — i. Westwood's specimens were bred 

 from galls of Qiiercus palustris received from U. S. (Papilio II., p. 97). 

 2. The size is nearly the same (Gallivora, alar expanse 8 lines). 3. '■'■Legs 

 yellow, with a dark ring around the tibice near the tips" characterizes 

 this feature exactly, especially true of the hind tibiae ; the first and second 

 pairs are yellow, with more or less blackish on the outside of the tibial 

 extremities. 



The sexes of what I take to be yEgeria gallivora agree almost exactly 

 in size and closely in ornamentation ; the lower part of the front and a 

 ring about the eyes milk white, above the white of the front shades into 

 yellow, which extends about the first antennal joint, and is overhung by 

 rather long blue-black scales, concolorous with the ground colour of 

 thorax and abdomen ; the palpi are yellow, blackish above ; and the 

 abdominal bands are two in both sexes, narrow in the male, the first 

 narrow and the second broad in the female. 



Although my material is scanty, I have reached the following con- 

 clusions regarding these gall-feeding and evidently inquiline species from
