The vestitnre is hairy with only a slight admixture of flattened 

 hair, forms no obvious crest, but does form a well-defined basal tuft. 

 Abdomen with only a loose dorsal tufting at base. Antennae of male 

 like those of indela. 



The genitalia of the male are similar to those of indela and coii- 

 radi, but have the clasper distinctly longer and the margin of the 

 harpes different in outline. Two figures of this form, taken from 

 specimens differing in appearance and from dift'erent localities, agree 

 with each other and differ equally from the figure of indela. 



It is very easy to mix this form with indela and I was strongly 

 inclined to consider them as identical until I noted the genitalic dif- 

 ferences, slight as these are. But, once a series is separated out, the 

 neat transverse lines, the well-defined median shade and rather con- 

 spicuous dark marking of the reniform emphasize the species. Withal 

 the two are very close and, in the females especially, it will be easy 

 to confuse them. The males are much more readily discriminated. 



Agroperina pendina, new species. 



Ground color rather deep luteous red-brown. Primaries darkening a 

 little outwardly, so that the concolorous s.t. line is slightly relieved. Median 

 lines lost or only traceable ; t.a. line usually all gone ; t.p. line more usually 

 traceable and sometimes accompanied by a slightly paler shading. Claviform 

 lost in all the specimens before me. Orbicular usually traceable, often lost 

 entirely, never well-defined. Reniform of the usual constricted type, laterally 

 often with pale defining lines and inferiorly dark filled. There is only the 

 vaguest trace of a median shade in any specimen. Secondaries distinctly 

 yellowish, with a rather definite, broad, smoky outer border, a narrow median 

 dusky line, and a more or less obvious discal lunula. 



Expands, 35-43 mm. = i. 40-1. 70 inches. 



Habitat. — Calgary, Alberta, in July; Winnipeg, Brandon, Miniota, 

 Manitoba, June and July; Olds, British Columbia, August. 



Differs from all the other species in the uniform deep reddish 

 shade of head, thorax and primaries, on which latter the usual macu- 

 lation is almost obsolete. The yellow color of secondaries with the 

 unusually definite outer border is also quite characteristic and tends 

 to differentiate the species. It is really nearer to indela than to 

 lineosa in character of primaries, though it resembles the latter more 

 nearly in the secondaries. A series of 13 males and 6 females is 

 before me for comparison. 



The vestiture is mostly hairy with some flattened hair intermixed,
