Subgenus Anarthropus ^^ new subgenus 



The subgenus is known to include two species; of these one, 

 C. (A.) saltans (Scudder), is North American and the other, 

 C. (A.) javanicus (Redtenbacher),^^ is Javan. 



Type of subgenus. — Conocephalus saltans [Xiphidium saltans] 

 (Scudder). 



Subgeneric Description.- — Prosternum unarmed. Subgenital 

 plate of male of the normal type found in the genus; distal margin 

 transverse, bearing minute styles laterad. Ventral margins of 

 cephalic and median femora armed with six well spaced spines. 

 Caudal tibiae with dorsal and ventral pairs of distal spurs absent, 

 armed at the distal extremities with a single pair of well-de- 

 veloped median spurs. Size small to very small for the genus, 

 form rather slender.

and 15; XX, 19.)

part.) [Red River Settlements, Manitoba.]

^^ From a.papdpos=weak and 7roi)s=foot, in allusion to the missing dorsal and 

 ventral pairs of spurs of the caudal tibiae. 



^s Abh. k.-k. zool.-botan. Gesell. Wien, xh, p. 526, (1891). The male of this 

 species has the cercus similar to that of saltans, but with tooth exceedingly long, 

 evenly and decidedly curved downward. 



"Single type here designated: 9; Platte [River, Nebraska], (Ilayden), 

 [M. C. Z.]. Measurements; length of body 12.8, of tcgmen 2.7, (caudal 

 femora missing), of ovipositor 13.7 mm.
