ably a species of Pimpla, which had devoured the spider's eggs. The 

 greenish-bkie reflections of the head and thorax of the females, and the 

 brigh! coppery gleam of the smaller males, make these little creatures, 

 when alive and hurrying to and fro with trembling antennae, objects of 

 considerable beauty. Mr. Howard records the species (Pjoc. Ent. Soc, 

 Wash., Vol. II., p. 299) from James Island, S. C; Brooklyn, N. Y.; 

 Sea Cliff, L. I.; Washington, D. C; and Los Angeles, Cal., showing a 

 very wide distribution. 



Telenomus, n. sp. ? 



From two eggs found attached, and side by side, on the upper sur- 

 face of a hickory leaf, I obtained thirty-one individuals (25 $ , 6 (J ) of a 

 Telenomus, which appears to be undescribed, but as the genus is such an 

 extensive and difficult one I do not care to name it. The eggs, which 

 are those of our beautiful pale green, swallow-tailed Luna moth, are round 

 and flattened ; white above and below, and surrounded by a dark brown 

 band. They are about 2 mm. in diameter, and not much more than 

 I mm. in thickness, so that when one was tenanted by at least sixteen 

 larvaj, their quarters could not have been over spacious. It requires 

 somewhat careful examination of the egg to find the minute hole from 

 which the parasites issued. 



AcoLoiDES SAiTiDis, Howard. 



From the same batch of spider-cocoons which produced the seventeen 

 examples of Pezomachus Fettitii, there came forth, a few days later, a host 

 of minute Prototrypids, which seem to belong to the species named as 

 above by Mr. Howard (Ins. Life, Vol. II., p. 270), and constituted the 

 type of his new genus ; the type specimens having been bred from eggs 

 of the spider Saitis pulex. My specimens differ from the description 

 only in having the apex of the first abdominal segment yellowish. They 

 commenced to appear on June 4th, and by the evening of June 6th there 

 had issued 160, nearly all of which were females. The total number that 

 came forth was 206, consisting of 162 $ and 44 $. Such figures might 

 indicate this to be a very common insect, yet I had never met with it in 

 my collecting. Previous records for the species are Lincoln, Neb., and 

 Oxford, Ind. 



Chrysis nitidula, Fabr. 

 One example of this beautiful green Chrysid was bred from an 

 almost black cocoon, which was found in a cell of Odynerus catskillensis,
