way to the tip, and one transverse carina near the base, the series enclosing 

 six quadrate areas, the posterior series, of which are open behind. Remainder 

 of metathorax strongly, roughly and irregularly rugose. Abdomen slender 

 and rather broad at the tip, no trace of ovipositor preserved. First abdominal 

 segment as long as the metathorax, enlarged rather gradually at the apex; 



second a very little longer; 

 the two together as long as 

 the entire thorax. Legs as 

 usual, apparently entirely 

 dark colored. Wings hyaline ; 

 stigma very narrow, reddish 

 fuscous; veins fuscous. Sub- 

 median cell longer than the 

 median by a distance equal 

 to one-third the length of the transverse median nervure. First re- 

 current nervure received a little beyond the basal third of the discocubital 

 cell; the second, the length of the transverse cubitus beyond the tip of the 

 cell. Discocubital vein bent distinctly at the middle, forming an angle of 

 about 135° with the discoidal nervure.

 which I believe belong to this species, although their color is more like 

 that of the following species, the abdomen being reddish, lighter on the 

 head and thorax. They are somewhat longer, 12 mm. in length, but 

 the wing venation is identical. 



Anomalon excisum, sp. now (Fig. 53.) 



Female. Length 16 mm. 

 the abdomen lighter reddish 

 brown. Antennae long, 

 many jointed, involute to- 

 ward the tips where the 

 joints are about one-half 

 wider than long; basal flag- 

 ellar joints more nearly 

 quadrate. Thorax higher 

 than usual and short, less 

 than twice as long as high 

 when seen from the sides.
