GEOLOGICAL SURVEY OF THE TEERITORIES. 729 



Species not belonging to Odonata. 



HET^RINA. 



E. Californica, Hag. Syn. N. Amer. Xeurop., 59, 2. 



The ti-cigments of three males are not to be separated from the type 

 in my collection. (Some fragments.) 



POLYSTGEOHOTES. 



P. punctatus, Hag. Syn. I^. Amer. Neurop., 206, 1. 



Very common everywhere in the whole United States. (Kumerous 

 specimens.) 



• STATHMOPHORUS. 



Spec. — Only a male related to St. Argus, Harr., perhaps distinct. The 

 male of St. Argus is still unknown. 



• PTERONARCYS. 



Ft. Californica, Hag. Syn. N. Amer. Neiirop., 16, 5. 

 A female ; a decidedly western sijecies. 



■ MYRMELEON. 



M. diversus, nov. sp. 



Brown, covered with grayish powder; head pale yellowish near the 

 mouth and the eyes; two black spots on the clypeos; front largely 

 shining black, brown mat behind the antennae; on each side of the occiput 

 a yellow spot, and near the middle a yellow band, attenuated and inter- 

 rupted in the middle ; antennse short, black, annulated finely with yellow, 

 the tips enlarged brownish; palpi yellow, the last joint black; last joint 

 of the labial i^al pi longer, ovoid, black, cylindrical at the truncated tip; 

 prothorax quadrangular, a little narrower and rounded before, dull yel- 

 lowish, with two interrupted brown lines in the middle, and one on each 

 side, not reaching the anterior part; thorax and abdomen brown, a final 

 yellowish triangular spot on the segments; legs yellowish ; femora be- 

 hindin the middle, tibitie inside, and basal joint on tip black; spurs as long 

 as the first joint; wings hyaline, veins yellow, spotted with black on the 

 radius, and most of the small furcations; stigma small, whitish. The 

 species belongs to the genus Myrmeleon, and is related to the M. formi- 

 carium. I believe a specimen in very bad condition, from the Pecos 

 Eiver, W. Texas, belongs here. (Two si:)ecimens.)
