evident at middle. The transverse lines so far as jireseiit are distinct, 

 sin<^le, and crennlate. 



Vocalis is slig'litly narrower winj^ed, tlie ordinary spots not marked; 

 hivenu.sla is l)nt a dark form of this s])0(;ies. 



PallidicoUis and <>iK(clfr<>iis ;\vo. broader wiiift'ed, the ordinary spots 

 are distinct, niorc^ oi- less marked by a dark shade in ceil. In the former 

 si)ecies the head and collar are, <;rayish whire, tlu^ jnimaries ocherons 

 on disk, theordinary s[K)ts conllnent. In the latter the front isblaekisli, 

 the i)rimaries are bluish gray, the ordinary spots not conlluent. 



Jliiruspica and sicrrw are lar^e, broad-winced species, the outer 

 mar«;in ()bli(|ue, but ratlier regularly rounded. _ 



The former has the ti-ausverse lines distinct, crennlate; the latter 

 has them scarcely evident, but so far as traceable they are even. 



So far as the genitalia of the S are concerned, they have not been 

 examined in roc((Iis, pallidicoUis, opdvifronK^ and tcppcri, females only 

 of these species being procurable. 



The other species agree in having the clasper distinct, simple, and 

 corneous, slightly dilfering in length and degree of curvature. The 

 harpes furnish the variation. 



In lubricans the entire armature agrees with that of the inciris gronp, 

 with which, by tlu^ hye, this species has been hei'etofort^ associate(l. It 

 dilfers, however, in structure of palpi, the small head and the obtuse 

 primaries. 



In ('lau(lesfi)ia, sicrr(V, hdnispica, ami harihe the harpes are alike, 

 regularly tapering to a blnnt ])oint and semicorneous. 



In atrifrons 'm\(\. piscipellis the harpes are broad to tip where they are 

 emarginate, the i>rojecting points hardly acute — the superior longest. 



Clemens is in some respects intermediate between the hanispiea and 

 clandesthui types, approaching most nearly to the clandeatind series, 

 from all of which it differs by the luteous gray color.
