Color deep black, sometimes tinged with ferruginous on the 

 base and apex of the pronotum toward the median line. Elytra 

 white, the clavus and broad apex of the corium as far as the 

 costal area piceous; large disk of the membrane piceous black 

 omitting a white spot or ray at the basal angle. Venter piceous, 

 polished. Posterior flap of the metapleura scarcely paler. Basal 

 two joints of the antennas dark ferruginous, the tip of the second 

 infuscated; third and fourth black. Legs dark ferruginous, the 

 intermediate and posterior femora piceous except at apex; tibiae 

 with the usual pale annulus covering most of their length. 



Described from three female examples taken at Hot Springs, 

 Arizona, by Mr. E. A. Schwarz and kindly sent, to me for study 

 by Mr. Heidemann bearing the MS name here employed, and 

 seven examples from the National Museum taken on June 2 2d 

 at the same locality by Messrs. Barber and Schwarz. This is a 

 very pretty species a little larger and more clearly marked than 

 disconotits from which it may readily be distinguished by the 

 black clavus and apex of the corium. 



3. Crophius lieidemanni n. sp. 



General aspect of the preceding but 

 with the clavus and corium entirely pale. 

 Antennae slender; basal joint scarcely 

 surpassing the tip of the tylus; second 

 long; fourth but little thickened, slightly 

 longer than the third. Callousities little 

 elevated, punctured like the adjacent 

 surface; anterior half of the metaster- 

 num deeply sulcate; tooth of the anterior 

 femora apparently obsolete. Elytra mi- 

 nutely and obscurely punctured, these 

 punctures concolorous and scarcely ar- 

 ranged in lines on the clavus. Length 3 1/2 mm. 



Color deep piceous black with slight bronze reflections; 

 median line and humeral angles of the pronotum touched with 

 ferruginous; second and third antennal joints fulvous. Elytra 

 soiled white, immaculate; the membrane deep smoky brown 

 with a pale apical border along the outer margin of which is a 

 row of fuscous points; femora piceous black, their apex and the 

 tibiae and tarsi yellowish. Venter piceous black, polished.
