388 My. W. L. Distant on Pentatominae. 



Genus DiCTYOTUS. 



Dictyotus cequalis. 



Pentatoma csquaHs, Walk. Cat. Het. ii. p. 310. n. loO (1867). 

 Dictyotus Roei, Ball, (nee Westw.) List Hem. i. p. 140, pi. iii. fig. 4 

 (1851); Dist. Ann. & Mag. Nat. Hist. ser. 7, vol. iv. p. 434 (1899). 



Since publishing my note on this species [supra] I have 

 examined Westwood's type, and find it is quite distinct from 

 the species identified by Dallas in the British Museum coUec- 

 tion as D. Roei. Walker's name therefore now stands, 

 though he described the species in a wrong genus and irre- 

 spective of it being represented by a series in Westwood's 

 name and under the genus IHctyotus. 



Dictyotus detersus. 



Mormidea detersa, Walk. Cat. Het. iii. p. 554 (18t)8). 



Somewhat the shape and form of D. similis, Dall. Dicty- 

 otus requires revision ; all the species which Dallas included 

 in his genus do not appear to be congeneric. 



Genus Eurinome. 

 Eurinome inconspicua. 



Pentatoma inconspicua, Montiouz. Ann. Soc. Linn. Lyon, (2) v. p. 249 



(1858). 

 Pentatoma cireiimdata, Walk. Cat. Het. ii. p. .307. ii. 137 (1867). 



Eurinome marginalis. 



Pentatoma maryinalis, Walk. Cat. Het. ii. p. 306. n. 136 (1867). 

 Pentatoma submarginalis, Tryon, Ann. Queeusl, Mus. ii. p. 16 (1892), 



Mr. Tryon's description exactly represents Walker's type. 

 AValker's description of this species is more than usually 

 careless and incomplete. 



Genus Peribalus. 

 Peribalus dubius. 



Pentatoma? duhia, Dall. List Hem. i. p. 237. n. 10 (1851;. 



Peribalus abbreviatus. 



Holcostethus abbreviatus, Uhler, U.S. Geol. Sur v. Montana, 1872, p. 397.
