A Peculiar Neuropteroid Insect from Colorado. 

 Eomerope gen. nov. (Meropidse.) 



Rather stout-bodied, with the end of the abdomen formed 

 somewhat as in Dittacus, or nearer, perhaps, to the type of 

 certain Trichoptera ; legs with many very strong spines ; wings 

 shaped much as in Merope, but more elongate, and at the same 

 time with the costal region more strongly arched, and includ- 

 ing (between the costa and subcosta) four longitudinal series 

 of cells. 



Eomerope tortriciformis sp. n. 



$ . General aspect that of a tortricid moth ; length 13 mm ; 

 head small ; width of thorax about 4 ram , of abdomen about 3-J-, 

 both no doubt somewhat widened by crushing ; color of body, 

 as preserved, pale ferruginous, the apex of the abdomen darker, 

 and a dark chitinous plate (? ventral) in the region of the basal 

 half of the first abdominal segment (fig. 3) ; end of abdomen 

 not elongated, but bearing a pair of thumb-shaped obtuse 

 harpes, directed obliquely upwards (fig. 2) ; the uncus or corre- 

 sponding structure short and apparently obtuse, without an 

 upturned point ; legs with short femora (hind femur about 3 mm ), 

 but rather long and slender tibiae and tarsi ; (hind tibia about 

 5 mm ), the tibiae (at least) with delicate appressed hair 2 and 

 numerous very large spines (fig. 1) which are finely striated 

 longitudinally (fig. la). The structure of the tarsi, the antennae, 

 mouth-parts, etc., cannot be seen. 



Wings as preserved pale reddish, nearly the color of the 

 shale, faintly striated by the slightly darker veins but without 

 spots or bands ; anterior wing 15-| mm long, and about 4 broad 

 (the exact breadth difficult to determine), with the basal part of 

 the costa strongly arched, but the apical two-thirds nearly 

 straight (the costal outline much as in Apochrysa) ; apex 

 rounded. Hind wings about 13 mm long and 3 broad, more 

 slender than the anterior. 



Venation of anterior wings. — Subcosta remote from the 

 costal margin, leaving a large space in which there are for a 

 considerable distance four longitudinal rows of cells. The first 

 upward branch bounds basally two large cells only, but the 

 second branch curves forward and runs parallel with the main 

 stem of the subcosta, and between it and the costal margin are 

 three rows of cells, the second and third of the middle row 

 being hexagonal (this is shown, better than it can be described, 

 in fig. 5) ; toward the apex of the wing the symmetry is some-
