tlie genicular arc black 5 hind tibiae luteo-testaceous or flavescent, the 

 spines black-tipped. Abdomen sparsely and coarsely punctate. 



Length of body, female, 22 mm.; antennae, 6.75 mm.; tegmiua, 3.1) 

 mm.; hind femora, 11.5 mm. 



One female. Saltillo, Nuevo Leon, Mexico, March 21-28, E. Palmer. 



This species differs from the preceding by its truncate tegmina, paler 

 hind tibiae, more uniform and generally lighter coloring, and the wider 

 interval between the mesosternal lobes of the female, which is here 

 almost or quite as wide as the lobes themselves. 



3. CONALCAEA NEOMEXICANA, new species. 

 (Plate II, fig. 9.) 



Ferrugineo-testaceous above, heavily marked with black, testaceous 

 beneath. Head testaceous, with a flavous tinge, flecked with fuscous 

 on the sides, and heavily infuscated above with a narrow streak of luteo- 

 testaceous behind the middle of the upper half of the eye, separating a 

 fuscous patch above from a black patch below; fastigium shallowly 

 and interruptedly sulcate, the frontal costa punctate, sulcate in its 

 middle half, the rest of the face and genae almost equally punctate; 

 antennae?. Pronotum scarcely widening posteriorly, with hardly any 

 indication of lateral carinae, the hind border very feebly emarginate, 

 the disk almost uniformly ferrugineo-testaceous, the upper half of the 

 lateral lobes of the prozona piceous, cut in the anterior half by an 

 oblique luteous streak, the lower half luteo-testaceous ; thoracic epimera 

 black. Tegmina enlarging gently from the rather narrow base to the 

 middle of the distal half and then well rounded, fully as long as the 

 prozoua, black, with mostly luteous veins. Hind femora with the outer 

 face livid, streaked with black above, the upper face ferruginous, the 

 lower pale green, separated from the outer face by a dark-green carina, 

 the genicular arc black ; hind tibiae reddish luteous^ the spines pallid, 

 with black tips. Abdomen, at least in its basal half, together with the 

 ineso- and metanota, black or blackish ferruginous, with a narrow 

 ferrugineo-testaceous median stripe, the black narrowing and finally 

 disappearing posteriorly, coarsely punctate. Supraanal plate of male 

 long triangular, tectate, with a slender and deep percurrent median 

 sulcus, and the lateral margins gradually raised a little; furcula con- 

 sisting of little more than the thickening of the adjoining edges of the 

 parted halves of the last dorsal segment; cerci very much as in C. 

 miguelitana, but more contracted in the middle, wider beyond, with the 

 upper margin in consequence more strongly sinuate; terminal tubercle 

 large and extending beyond the posterior margin of the subgemtal 

 plate by a greater distance than the latter is removed from the tip of 

 the supraanal plate. 



Length of body, male, 19 mm.; tegmina, 4 mm.; hind femora, 11.25 

 mm. 



One male. Silver City, Grant County, New Mexico (L. Bruner).
