C. SASAKI. 



by Mr. L. O. Howard. 5 The brief description of the parasite is 

 as follows : 



Female. — Length 0,93 mm. Expanse of wings 1.791 mm. Head 

 large and broad, light orange yellow in color ; vertex much expanded, 

 on which lie three crimson red ocelli, which are widely separated from 

 each other. Eyes dark brownish red, antennae 8 jointed, the basal or 

 1st joint is longer than the rest, the three terminal joints forming a club 

 are somewhat larger than the preceding joints. Thorax more or less 

 flattened, less broad than the head ; green yellow in color with dark 

 greyish brown peripheries, mesoscutum and mesoscutellum larger and 

 broad ; the latter nearly triangular. On each parapside there lies a single 

 black roundish spot. Wings transparent, hairy, but almost none 

 near the base, no hairless line on the surface. Marginal vein so long as 

 submarginal, the stigmal very short. The hind wing long spear shaped ; 

 at the middle of the front margin lie 3 hooks, while the posterior fringed 

 with long ciliae. At the distal end of each tibia, is a short spur. The 

 hind legs much larger than the others. The abdomen sessile, nearly 

 compressed cone in form. Its broader middle portion is about twice as 

 broad as the thorax. At the lateral side of the tergal piece of the 6th 

 abdominal segment, there lies a small excavation, in which are grown two 

 long hairs (Fig. 8 ; Fig. 8, a ; Fig. 8, b. Tab. IV). 



In the specimens of the scale allied to the pernicious scales collected 

 by myseef, I have often found a roundish or rather small irregular opening 

 in most of the scales, which is evidently perforated by the parasitic chalcis- 

 fly, (Fig. 9. Tab. IV).
