Say, /. c., applied the term " terminal segment " to the ninth abdomi- 

 nal segment, as is evident from his statement that the yellow spot on the 

 terminal segment occupies all the side thereof and is conspicuous. His 

 type had yellow dorsal spots on 7 and 8 but not on 9. He says indeed 

 that the dorsal yellowish line exhibits "a spot only on two of the dilated 

 segments," but when this is so in our Gomphime it is the last of three 

 dilated segments, / <'. the ninth, which is unspotted. Walsh says, /. c., 

 p. 240, that Say described a yellow dorsal vitta on 9 and a small median 

 dorsal yellow spot on 10, but I cannot find anything to this effect in Say's 

 description.

Gomphus externus Selys. 



(i. f.vteniiis Selys, Mon. Gomph., p. 411, pi. 21, fig. 2. 1858. 



(N. B. The female is said to have " pieds comme chez le male," 



while the male's femora are said to have " une bande, externe mal 



arrete aux autres [femora than the ist and 2nd]. This is a character 



more like crassiis ; so also is fig. 2 //, of the vulvar lamina, more like 



crassus. On the other hand, chars, jo and 12 of our <M ti -runs agree 



with this description and not with those of crassus). 



(,'. I'.vtenins Selys, Bull. Acad. Belg. (2) vii, p. 540. 1859. (Since 



this description is practically only an abridgment of that of the Muimgr. 



the remark above made concerning the vulvar lamina applies here also).

sobri nits is placed as a synonym.)
