C. q. majalis n. sp. 



9 Head transverse, black, nearly smooth, but under a powerful magnifier 

 presents a fine netted appearance; face smooth with a very few short white 

 liairs; mouth brown, tips of the mandibles black. Antennce long, with 13 joints, 

 first and second short, third very long and enlarged at the upper end. These, 

 except the slightly enlarged portion of the third, are a pale yellowish white, 

 the remaining joints a light opaque brown. Thorax black, smooth and shin- 

 ing; without any grooves or striae whatever on the mesothorax. Scutellum 

 smooth, separated from the mesothorax by a broad shallow groove ; fovese want- 

 ing; marked posteriorly by two deep transverse grooves, causing three transverse 

 ridges above the insertion of the abdominal peduncle. Feet white with a tinge 

 of yellow, like the basal joints of the antennae. Abdomen black, smooth : in dry 

 specimens shrunken and wrinkled. Wings large with a faint duskiness and a 

 dusky cloud resting on the first transverse vein; veins dull brown ; areolet pre- 

 sent; radial area open, long and very narrow. Length (dry) .09.

 feet and the first and part of the second segment of the abdomen very light
