19181 W~COX-A Pa~m'te of the O~ientul Moth 17 type. An analogous case is found in the vertebrates in which the excised heart of such a comparatively generalized type as the frog is much more resistant than the heart of a specialized mammalian type like the dog, the caty or man.
There is every reason to think that pulsatile vessels will be found in mosty if not ally families and genera of the Hemiptera and Homoptera. Their discovery in the Aphididzz simply adds to the already convincing evidence of the close relationship of these two. groups.
ASCOGASTER CARPOCAPSB, A PARASITE OF THE ORIENTAL MOTH.
BY A. M. WILCOX,
Gipsy-moth Assistant, U. S. Bureau of Entomology. The Oriental moth, Cnidocampa $uvescens Walk., a native of' Japan was first discovered in this country in 1906. Although at
present the infestation is confined to a small area, there is a possi- bility of the moth becoming a widespread pest. Several attempts have been made to rear parasites from the larv~ and cocoons of the moth, but as far as the writer knows, none of these previous attempts have been successful. During the spring of 1917 several of the cocoons were collected in Dor- chestery Mass., and placed in rearing boxes. During the month of June the adults began to appear and a single Braconid parasite emerged at the same time. The specimen was determined by Prof. C. T. Brues of the Bussey Institution, Harvard Universityy as Ascogaster carpocapsce Viereck. The species was first described as Chelonus curpocapsce in 1909 by Viereck.1 The Codling moth, Carpocaps~ pomonella was named as the host insect. The species may be recognized by the absence of segmentation on the abdomen and by the presence of four transverse nipple-like prolongations on the outer and upper edge of the posterior face of the metathorax. It can readily be separated from Chelonus ~LSSUS pro^.^ a commony similar speciesy by the absence of pubescence on the eyes, and the different wing venation, the first submarginal and first discoidal cells being separated in A. carpocapsm, while in C. $ssus they are confluent.
