^cudder. The structure of the insects here inchidod is different from 

 all other of our Fhasniidse, as is shown by the legs being attached 

 beneath the body in such a manner as to conceal the coxa; from above. 

 iThe three-jointed tarsi are also peculiar to this su})family. The three- 

 jointed tarsi are obviously the result of a imition of the first three seg- 

 ments of the normal pentamerous phasmid tarus. This is indicated by 

 the lower surface of the first segment showing obscure segmentation 

 where the original segments have united. 



We have but one genus of this interesting subfamily in the United 



States. 



TIMEMA Scudder. 



Timema Scudder, Can. Ent., XXVI, 1895, p. 30. 



The characters limiting this genus are: 



General form short and broad, not linear, head subquadrate, no 

 longer than broad, as broad as the thorax. Antenna? much longer 

 than the anterior femora, basal segment very large, three times as 

 long as broad, enlarged apically. Prothorax quadrate, not narrowed 

 anteriorly, no shorter than the metathorax and without distinct odorif- 

 erous glands ; meso- and metathorax subequal in length. Legs short and 

 stout; cerci of male forcipulate, irregular in shape and curving 

 inwards, of female stout, vertically flattened and straight, in both sexes 

 longer than the last abdominal segment. 



We have a single species.

 This species, the tvpe of the genus, has never been described Dr. 

 Scudder has very kindly furnished the following description, which is 

 here published for the first time: 



Head large, thorax depressed, abdomen depressed cylindrical, expandn^g some- 

 what posterfokly, the whole body smooth, glistening a l^^le nearly umtormlute.- 

 Ltaceous with a'faint greenish tinge, the abdomen slightly '^^^^^^^^ 

 thorax, the latter striped longitndinally and narrowly with brownish fuscous most 



distinctlyin a submarginal stripe, in which are ^Zri'T'^'tr'tCln^T^nZ 

 about as Ion- as head and thorax together. All the legs short, behind femora 

 abo: ^^lon^as the first three abdominal segments. Last ^^^^J^ 

 male somewhat expanded and tumid, the ^ind nmi^u. sinuato^runcate th^^^^^^^^
