Four maU'H, 5 females. I'ort Wortli, Tarrant County, Texas, May, 

 (fXo. 70')] U.S.N. M , — Kiley colleeticm); Columbus, Colorado (>ounty,

This apeeies resembles /*. pumtntn to sueh a degiee as with difticulty 

 to be <listinguish(Ml from it, except by the abdominal ap}>einlagesof the 

 male, which are rennirkably distinct. Tiiere is no sign in the female of 

 tlie dark mediodorsal fusiform patch on the pronotum.and the coloring 

 of the female in both species is very variable. • 



There are two other forms of Paraidennma known to me, which I 

 deem probably distinct from either of the above, but being known 

 only by the female, i only allude to them. Both have relatively heavy 

 hind femora. 



One is almost wholly olivaceous, the abdominal carina marked with 

 yellow, and with yellow shades upon the sides of the dorsum of the 

 thorax; it comes from Carrizo Springs, Texas (U.S.N.M.). 



The other is almost wholly yellowish testaceous, with no dorsal stripe 

 and relatively feeble and fleeting lateral stripes; it comes from Dallas, 

 Texas (U.S.N.M.), and Veuis Mecas, San Luis Potosi, Mexico, January 

 C, E. Palmer. 



13. AIDEMONA. 



(aidi'f/iiooi^, modest.) 



Aidemona Hruxxeh, R<^v. Syst. Ortb,, 1893, p. 145. 



Body com])act, moderately slender, parallel sided but enlarged at the 

 niesothorax. Head not ])rominent, the vertex well rounded, rising 

 above the level of the pronotum, the space between the eyes narr(>w 

 but not veiy narrow, the face broadly rounded and a little retreating: 

 frontal costa a little pronnnent above, broad, much broader than the 

 interspace between the eyes, plane, percurrent, subequal, and heavily 

 punctate: eyes moderately prominent but little more so in the male 

 than in the fennde, rather large, l)r(?ad ovate, much larger than the 

 subocnlar portion of the genae; antennae slemler, rather shorter than 

 the head and jnonotum together. Pronotum scarcely enlarging poste 

 riorly, transversely quadrate, the dorsum plane or very feebly conv^ex. 

 with the lateral lobes set sharply at right angles to it, but otherwise 

 with no raised lateral cariuae, a feeble median carina on metazona only.
