Parotermes fodin^ nov. sp. 



Head oblong obovate, half as long again as broad, the eyes large, 

 circular, about one fifth the diameter of the head, slightly jji'ojecting 

 beyond the sides, the anterior edge near the middle of the head. 



Pronotum transversely lunate, as broad as the head, less than twice 

 as long as broad, the front margin regularly and considerably concave, 

 the hind margins and sides forming one uniform strongly convex curve, 

 the anterior lateral angles rounded off. Meso- and metanotum ob- 

 scurely preserved, but apparently formed much as in the other species, 

 the mesonotum being of about the same width as the pronotum. 



Abdomen rather long and comparatively slender, scarcely if at all 

 exceeding in width the parts in front, the sides being unusually par- 

 allel, the tip well rounded, the whole as long as the rest of the body. 

 Abdominal appendages very small, stout, being only a little more than 

 twice as long as broad, largest in the middle, and tapering either way, 

 the tip blunt, the whole not longer than the diameter of the eye. 



Legs poorly and partially preserved in a single specimen, showing 

 them to be much as in P. Harjenii^ the hind tibia being only a little 

 shorter than the width of the mesothorax. 



AVings four times as long as broad, the middle of the front pair 

 reaching the tip of the abdomen ; the exact form cannot be made out, 

 but the costal margin is straight until very near the tip, and the hind 

 border appears to be uniform and to make the wing slightly broadest 

 just beyond the middle. The submarginal vein is unusually long, 

 running into the costa only a little before the middle of the wing. 

 The mediastinal terminates not far beyond the middle. The scapular 

 vein has five or six branches in the front wing, generally five in the 

 hind wing, the first appearing always to originate at the end of the 

 basal third of the wing. The inferior nervulcs of this vein and 

 the course of the branches of the veins below cannot be determined in 

 any of the specimens, but there are faint indications of their presence, 

 and nothing in them appears to distinguish this species by any marked 

 peculiarities from the others of the genus. 



This species differs from the others here described in its consider- 

 ably smaller size, slender abdomen, and much smaller abdominal ap- 

 pendages. 



Length of body, 9 mm. ; breadth of thorax, 2 mm. ; length of front 

 wing, 13 mm. ; breadth of same, 3.25 mm. ; length of hind tibia, 

 2 mm. , of abdominal appendages, 0.25 mm. 



Florissant. 4 specimens. Nos. 1247, 1253, 7608, 11190, and 14391.
