 Not Daihinia Sauss., Orth. Nova Amer., i. 14-15 (1859), < 



Tliis genus is remarkable for lacking the third tarsal joint of the 

 fore and hind legs. Brunuer (Monogr. Stenop., 60, foot-note) pre- 

 sumed this to be an abnormal condition found in a single specimen 

 seen by me ; but it was seen and specially remarked upon both by 

 Haldeman and Girard before me, and I have examined fourteen speci- 

 mens of both sexes, all of which agree in this particular except that 

 in two or three of them the fore or hind tarsi, or both, are broken, 

 so that it cannot be affirmed of them. There can be no question that 

 it is normal as no specimen of the two species has been found in which 

 the condition was different. 



Table of the Species of Daihinia. 



Hind femora of male about two and a half times longer than broad, 

 armed with 3-4 very large spines on the apical half of the outer 

 carina much larger than the others, the inner carina much more 

 feebly armed ; hind tibife armed beneath with a single subapical 

 spine brevipes. 



Hind femora of male fully three times as long as broad, the spines of 

 the outer carina nearly uniform and much less prominent than 

 those of the inner carina ; hind tibias armed beneath with a row 

 of spines . gigantea.
