in all specimens examined and was not noticed in tecta or wockei, but, as 
material of these latter two is very limited, it may readily be present 
when longer series are available. 
There is also a marked similarity between the genotypes of Pachnobia 
and Anomogyna in genitalia, but the latter genus shows in general weaker 
fore-tibial spining and a longer third palpal joint. 
Setagrotis Sm. 
1890, Bull. 38, U. S. N. M. 9 (type, planifrons Sm.). 
Eyes naked. Palpi upturned, third joint slightly porrect; second joint 
heavily but rather evenly fringed w T ith hair below and w r ith scarcely an 
indication of a pointed apical tuft; third joint smoothly clothed. • Front 
smooth. Male antennae finely fasciculate. All tibiae spined; fore tibia 
subequal to or longer than first tarsal joint, with complete inner row of 
weak spines; on outer side fringed w 7 ith hair with a couple of apical spines. 
Thoracic vestiture mixed, rather smooth, with fairlyVevidenU pro- and 
metathoracic tufts. 
Figure 38. Male genitalia of Seiagrotis planifrons Sm. 
Male Genitalia. Clasper narrow and tapering to a point apically; no 
corona and only an indication of a pollex; harpe strong, excurved, and 
attached by a bent rod of chitin to apex of sacculus. Clavus lacking. 
Uncus diamond-shaped with pointed apex. Juxta strong with produced 
apex. Vesica armed with bundles of short cornuti. 
The typical section includes planifrons 8m. and cinereicollis Grt., which 
are distinct species on genitaiic characters, the harpe of the former being 
broadened at the base and reminiscent of that of Group IV of Graphiphora. 
Radiatus Sm. very evidently falls here; it shows a better-developed pollex 
and a reduced uncus, but the vesica armature is the same. 
As a second group the w r riter includes atrifrons Grt. and piscipellis 
Grt. (with its races which have not been examined) . These show stronger 
spining on the fore tibiae wfith less prominent hair-fringe; the palpi are
