defined whorls at the extremities of the enlarged portion of each segment, 

 but there are a number scattered over the entire enlarged part ; antennae 

 equal in length to the abdomen. In dried specimens many of the anten- 

 nal segments in both sexes are considerably distorted, and the same may 

 possibly be true of living individuals ; third segment about one-half 

 longer than fourth. Mouth-parts yellowish; labial palpi long, com- 

 pressed, four-segmented, the third and fourth segrr ents two to three 

 times the length of the second, all bearing scattering, stout setae; labium 

 densely setose. 



Thorax light brown with a few scattering microscopic hairs on the 

 dorsum ; scutellum prominent, domed, yellowish, and with several long 

 bristles laterally. Wings large, hairy; second longitudinal vein (radius) 

 joining costa beyond the apex. Halter long, slender, clothed with hairs, 

 and dilated apically. Coxae large, hind pair extending to the third 

 abdominal segment; trochanter subcuboidal ; femur slender, gibbous 

 apically and extending beyond the tip of the abdomen; tibia of nearly 

 equal length and dilating gradually distally ; first tarsal segment very 

 short, second about equal to tibia, third one-half second, fourth a little 

 shorter, and terminal very short and with two claws (fig. 5). First and 

 second pairs of legs longer than third, all clothed uniformly with coarse, 

 slightly curved hairs similar to those of the wings and abdomen. 



Abdomen grayish, thickly clothed with hairs, and with long setse arising 

 from hind margin of segments, especially laterally. In the female the 

 fourth and fifth segments are slightly stouter, the posterior tapering to 

 the short ovipositor (fig. i). The male bears the terminal segments 

 partly curved over the back. Two lateral pieces support the large, 

 curved claspers, which are nearly as long as the segment and obtusely 

 rounded at the apex. They are borne in a crossed position with their 

 tips toward the base of the segment (fig. 7). Protruding below, the tip 

 of penis may be seen — represented in outline at fig. 6. Ovipositor of 

 female apparently short, eUipsoidal, and but slightly extruded. 



Length of body 0.075 ii^ch, of wing o.i inch. Described from four 

 males and eleven females. 



In the first sending of Mr. Barker on August 27, 1888, the Cecido- 

 rayids had probably been given out about the 1st of September, for upon 

 opening the box on September 12th, all except one example were found 

 dead. 



The second sending on August 13, 1889, when opened on September 7 th, 

 contained nine dead Diplosis with their pupa-cases. In 1892 additional 

 material was received from Mr. Barker, who had changed his residence to 

 another poition of the city in the meantime. Thus it would appear 

 that the insect has become one of those which regularly attack the melon 

 and that it is not confined to a single locality. 



In the box in which the above were bred, several Chalcids were found 

 in two species. They were sent to Washington for examination and 

 Mr. Howard returned answer that they were Lysiphlebus cucurbitaphidis 

 Ashmead, and Isocratus vulgaris Walker — in all probability parasitic on
