10 RESULTS FROM GIPSY MOTH PARASITE LABORATORY. 



the sides as well, below middle; metanotuni black; abdomen with a 

 black, rounded spot dorsally just below middle, abdomen also black 

 at tip; antennas brownish, with a whitish pile; all legs light yellow. 



In the markings the species is extremeh" A^ariable. A frequent 

 variation from what we ma}'^ call the typical markings as shown in 

 the illustration, is the absence of the black spot on mesoscutellum, 

 although sometimes it is represented b}' a minute central dot; the 

 occipital black spot is frequently lacking; the pronotal and meso- 

 scutal spots frequently become greatly reduced in size. On the 

 other hand, in many specimens the black spots become greatly en- 

 larged so as to make black almost the predominant color of the 

 insect. 



Male. — Length, 1.26'""^; expanse, 2.4.3'^'"; greatest width of fore 

 wing, 0.43'"™. Antennae yellowish, with abundant, long, white pile. 

 Color as with female, except that entire apical half of dorsum of 

 abdomen is black, and entire pronotum is black. There is almost 

 the same range of variation in size of black spots as with the 

 female. 



Described from 43 female and 8 male specimens reared from 

 cocoons of Gliiptajpanteles japonicus Ashmead, received from Trevor 

 Kincaid during the summer of 1908 from various localities in Japan, 

 and from other cocoons of the same species received from S. I. Kuwana 

 during the summer of 1909 from different localities in Japan. Named 

 after Prof. G. Ogima, Assistant Entomologist, Kyushiu Experiment 

 Station, Kumamoto, Japan, in recognition of his valuable services. 



Type. — No. 12681, U. S. National Museum; Gipsy Moth Labora- 

 tory Nos. 1623 and 1074. 



There is a single female of this species, labeled ' "Kumamoto, Japan, 

 reared 10th of May, 1907, by G. Ogima, egg-parasite of P. dispar.'^ 

 This specimen was not sent to the writer by Professor Ogima himself 

 directly, but either through Professor Kuwana or Mr. Kincaid, and 

 it is the receipt of this specimen which justifies the description of 

 this new genus and species in a paper on the egg-parasites of the 

 gipsy moth. Very large numbers of this parasite, however, have 

 been reared at the Parasite Laboratory at Melrose Highlands, by 

 Mr. Fiske, from the cocoons of the Glyptapanteles, and it is very pos- 

 sible that a mistake has arisen in Japan through the rearing of this 

 species apparently from an egg-mass of dispar which had been laid 

 over a mass of Glyptapanteles cocoons. Similar instances have 

 occurred before, notably in the case of Ashiae&d' sAhlerus clisiocampse, 

 which apparently came from an egg-mass of Olisiocampa but in 

 reality from Chionaspis furfura on the bark of the twig under the 

 egg-mass of the Lepidopterous insect. Similarly the writer's Iso- 

 dromus iceryse was apparently reared by Mr. D. W. Coquillett from 

 egg-masses of Icerya purchasi but in reality came from a Chrysopa
