A NEW GENUS OF STENOPELMATIN^ (ORTHOPTERA) FROM NEW MEXICO. 

 BY JAMES A. G. REHN AND T. D. A. COCKERELL. 



The material on which this genus is founded was collected in the 

 vicinity of Pecos, San Miguel county, New JMexico, in the summer of 

 1903, by Mrs. W. P. Cockerell. Two specimens were taken, the larger 

 of which is the type of the genus and species. It appears to be 

 doubtful that it is mature, but that it represents an entirely new type 

 is beyond question. The smaller specimen, taken July 21, is in such 

 condition and of such small size that nothing definite can be deter- 

 mined from it. 



SPILACRIS n. gen. 



This genus is a member of the Rhapidophorse, and belongs either to 

 the Tropidischise or represents a group by itself.

 reniform, prominent; antennse with the basal joint longitudinal, second 

 joint globose, third and succeeding joints longitudinal; palpi simple. 

 Pronotum concave, saddle-shaped, lateral lobes with the lower margin 

 roimded. Wings and tegmina absent.^ Anal styles aciuninate, rather 

 short. Anterior and median femora compressed, the posterior slender, 

 moderately expanded at the base, the apical portion attenuate. An- 

 terior tilDise imperforate. Tarsi without pul villi.

1903; on Fallugia. (W. P. Cockerell.)

Size very small; form slender, apter- 

 ous; surface sparsely haired. Head Avith 

 the occiput globose; the process of the
