580 PROCEEDESrGS OF THE NATIONAL MUSEUM vol. lu 



designated as paratypes. One, also from Paradise and collected by 

 O. C. Poling in June, was received from the Carnegie Museum. The 

 other two are from the U.S. National Museum. Of these, one is 

 from Douglas, Cochise Co., Ariz., July 1-7. The other, apparently 

 from Lord Walsingham's collection and determined by him, bears a 

 number of labels giving the following information: "cf — 136, 1889, 

 Wlsm. CoU.^ — Morrison, Arizona, 1881 — Collection C. V. Riley — Ana- 

 phora macrogaster Wlsm." 



Remarks. — Tliis subspecies may be distinguished from the others 

 of the macrogaster complex by its unipectinate antennae, from which 

 the name is derived. A single 9, received from the University of 

 Kansas and labeled "Douglas, Arizona, August, F. H. Snow," defi- 

 nitely represents one of the subspecies of macrogaster. However, 

 it was not collected in conjunction with any of the c? specimens I 

 have received for study, and thus can not be positively associated 

 with unipectinicorntis, also recorded from Douglas. Its external ap- 

 pearance is essentially the same as that of the 9 of laminicornus, 

 described below.

Figures 85-89 



Male. — Similar to macrogaster in habitus and general coloration. 

 Labial palpi elongate, recurved, extending somewhat beyond center of 

 thorax; diverging from head, thorax, and from each other distad; 

 basal and central segments approximately equal in length, apical 

 segment slightly longer than either. Eyes rather small, moderately 

 setose, anterior and posterior portions lashed. Antennae simple, 

 laminate; each process finely setose, laterally flattened, narrowly 

 separated from adjacent processes. Ground color of wings and abdo- 

 men rich brown. Forewings with whitish patches large, prominent. 

 Tip of abdomen with pair of prominent, lateral tufts; each tuft 

 composed of numerous, elongate, slender, brown and white scales. 

 Expanse: 17-21 mm. 



Female. — Similar to cT in general coloration. Labial palpi short, 

 closely appressed, basal portions recurved, apical portions porrect. 

 Eyes as in cf , but less heavily lashed. Antennae as in cf , but more 

 slender. Tip of abdomen without tufts. Expanse: 28 mm. Thirteen 

 cf cT and one 9 from Pima and Santa Cruz Counties, Arizona. 



Male genitalia. — Vinculum distinctive, consisting mostly of 

 ventral plate with caudal margin and laterocephalic extremities 

 broadly and evenly rounded and cephalic margin broadly emarginate. 



Tegumen broad, glabrous; lateral arm narrowing to point of articu- 

 lation with vinculum, margins somewhat sinuate; dorsal area not
