Eulophus theclae n. sp. 
S. Body short, abdomen shorter than the thorax. Body 
uniformly shining dark blue, smooth. Head fully as broad as the 
thorax. Front, including most of the vertex with the ocelli, 
deeply sunken (in dry specimens). Mouth parts dark brown, 
antennae simple, very short and stout, the joints being much 
shorter and thicker than in E. semideae. Eyes smaller than in 
semicleae. Thorax with the three lobes of mesoscutum very dis- 
tinct, the lateral lobes very large ; scutellum large and long, 
smooth, with two parallel, impressed, somewhat testaceous lines. 
Wings hyaline, veins as usual, subcostal dilated at end. Legs 
dark blue as far as tip of femora, which is whitish, like tibiae and 
tarsus, terminal joint of tarsi dark; all the legs alike. Abdomen 
large and broad, much broader and larger than in E. semideae, 
flattened, not much sunken in above, oval tip well rounded, not 
so hairy as in semideae ; concolorous with the rest of the body. 
Length .07-.08 inch. 
Differs from E. semideae, in which the antennae are very long 
and slender, by the very short antennae, and much broader, larger 
abdomen. The body is shining, not punctured, and the two 
parallel lines in the meso-scutellum seem characteristic of the 
species. 
Bred from pupa of Thecla calanus (T. inoratus) ; no females 
were bred, showing that the entire brood were males. 1 
Eulophus Saundersii n. sp. 
Three $. A minute species compared with E. semideae, but 
otherwise closely allied to it in structure and color ; the abdomen, 
however, is considerably shorter and thicker, being scarcely 
longer than the thorax, while in E. semideae it is as long as head 
and thorax together. Antennae of the same form as in E. semi- 
deae but much shorter, the joints between the second, and the 
club being no longer than broad, while in the other species (E. 
semideae) they are twice as long as thick ; they are brown and 
hairy. Wings much as in E. semideae, but the veins are much 
paler, less distinct. Legs colored much as in E. semideae. Tro- 
1 1 have also, June, 1881, bred a species of Tachina from what I suppose to be larvae 
of Thecla calanus found in the pig-nut hickory at Providence, R. I., just as soon as the 
leaves have expanded at the end of May.
