Nemobius exiguus Scudd., 14 1, VII, 1862, 429. 



Two forms of this, our largest and most common Nemobius, occur 

 in Indiana. In one (fasciatus) the tegmina reach to the end of the 

 abdomen while the inner wings extend to the tip of ovipositor. In 

 the other (vittatus) the tegmina of the female cover a little more 

 than half the abdomen and their cross-veinlets are coarser and much 

 more prominent than in TV. macnlatus. Those of the male cover 

 three-fourths of the abdomen. In this form the inner Wings are 

 wholly wanting in both sexes. As in most of the other species the 

 head and thorax bear many coarse, stiff black hairs. The ovipositor 

 is longer than in any other Indiana species, being about one-eighth 

 longer than the hind femora. 



The short winged form varies in color from a dusky brown to a 

 rusty black. When of the latter hue the black stripes on the head, to
