somewhal transversely so, the middle provided with a fairly con- 

 spicuous percurrent carina. Abdomen apicallj above dimly 5-cari- 

 nate .1- in some of the species of Cephalocoema. Supra anal plate 

 short, bluntly rounded at apex; subgenital plate as described above. 

 I 1 gs slender. Margins of hind tibiae 20-21-spined. 



General color dark olive-brown, with the lateral margins of the 

 head and prothorax flaxen-. Legs and underside testaceous. 



Length of body, d\ 64 nun., of head above, to. 5 mm., of rostrum, 

 2.05 mm., of pronotum, 12.5 mm., of anterior femora, 9 mm., of hind 

 ira, 22 mm., of hind tibiae, 22 mm., of subgenital plate, 6 mm. 



Habitat. — A single male, the type, is at hand. It was collected by 

 J. D. Haseman at Formosa, Bahia, Brazil, February 15th, 1908. The 

 type is deposited in the Carnegie Museum. 



This insect in some of its characters approaches the genus Cepha- 

 locoema, but in others certainly is distinctly a Tetanorhynchus.

•itat. — The present species is represented by at least eight male 

 specimens, which come from Corumba, Brazil, where they were collected 

 by II. H. Smith during March and April. There are also at hand 

 three females from the same locality and bearing similar dates which 

 I am inclined to label smithi, although they are comparatively small 

 and slender (85-88 mm. long) to go with the males. Possibly these 

 may be "subimagoes" or individuals which have matured with the 

 fourth instead of the fifth molt, as mentioned on a former page of this 

 paper.

Habitat. — There is a single female specimen of this insect at hand 

 which II. H. Smith took during October. It comes from Rio de Janeiro. 



As Brunner von Wattenwyl suggests, this insect has some char- 

 acteristics of Corynorkynchus as well as of the present genus.
