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 considerably 

 smaller size, slender abdomen, and much smaller abdominal appendages. 



Length of body, 9 mm ; breadth of thorax, 2""" ; 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. Four specimens, Nos. 1247, 1253, 7608, 11190 and 14391. 



2. HODOTERMES Hagen. 



Ha gen refers to this genus two fossil species from Oeningen and two 

 from Radoboj. Assmann also describes a species from Schossnitz, and one 

 of the Florissant white ants is referred here doubtfully. The fossil there- 

 fore nearly equal in number the living species, which are all inhabitants of 

 the Old World, the most northern species being found in Hgypt. 



HODOTERMES ? COLORADENSIS. 

 PI. 12, Fig. 6. 



Hodotermeiil coloradensis Scudd., Proc. Amer. Arad. Arts and Sci., XIX. 14-2-143 (1883). 



Mt-tanotum considerably narrower than the mesonotum, as long as 

 broad, tapering posteriorly, the front border straight, the hind border 

 rounded. Abdomen ovate, stout, less than twice as long as broad, the sides 

 full, as broad as the mesothorax, posterior extremity rounded. Abdominal 

 appendages long and slender, half as long as the metanotum, composed of 

 at least six or seven joints, slightly tapering, terminating very bluntly. 



Wings vcrv long, the middle of the front pair lying far beyond the tip 

 of the abdomen. Submarginal vein absent from all the wings. Jlediasti- 

 nal vein terminating at the middle of the front border. Scapular vein 

 parallel to the front margin, with at least four branches in both wings, and 

 in the front pair pretty certainly five branches, and perhaps six; the first 

 branch originates in the front wing at the end of the basal fourth of the 

 wing, in the hind wing a little farther out. 



This species is readily distinguished from all the other fossil Termitina 

 of North America by its very great size, the length of the wings being 

 double that of any other. Although the specimen is very imperfect, the
