NO 1124. RErrsrox OF THE MELANOPLiscrnnEit. 387 



suffused and confluent, forming infumate spots; and similar puncta 

 upon the thoracic pleura, all the femora, and the fore and middle tibiae; 

 antennae coarse, bluntly terminated, annulate with blackish brown, 

 which oddly occurs at the apex of one and the base of the succeeding 

 joint, the incisures excepted; frontal costa slightly narrower than the 

 interspace between the eyes, uniform in width, deeply sulcate; eyes of 

 female anteriorly truncate, not more than half as long again as the 

 anterior infraocular portion of the genae. Pronotum most sparsely 

 pilose, the metazona with exceedingly delicate punctuation and with a 

 very feeble median cariua, continued on the prozoua as an impressed 

 line only ; hind margin obtusangulate, the angle rather broadly rounded. 

 Tegmina subhyaline on the apical half or more, both veins and cross- 

 veins very pale testaceous ; wings hyaline, nearly as long as the teg- 

 niina, of ample breadth, with pallid veins and cross veins. Hind tibiae 

 and tarsi luteous, the spines black tipped, varying from eight to nine 

 on the outer margin in both sexes. Supraanal plate of male triangular, 

 rather elongate, with rounded acute apex, the surface with two high 

 and sharp, subparallel, convergent and then divergent, longitudinal 

 ridges, fading apically, including between them a rather narrow and 

 very deep median sulcus extending the whole length of the plate, but 

 shallow apically; furcula consisting of two distinct, not large, adjacent, 

 rounded lobes, projecting by half their length; cerci moderately broad 

 and slightly inflated at the base, at once narrowing, wholly on the 

 upper side, beyond straight, compressed, equal, scarcely incurved, 

 about one- third the width of the base, the tip rotmdly pointed, reach- 

 ing as far as the tip of the supraaual plate; infracercal plates concealed 

 when the cerci are recumbent; lateral margins of the subgenital plate 

 sinuous, the apical tubercle a little elevated, broad, subtruncate, and 

 subbitid as viewed posteriorly, pilose. 



Length of body, male, 19 mm., female, 28 mm.; antennae, male, 10 

 mm., female, 11.5 mm.; tegmina, male, 19.75 mm., female, 23.5 mm.; hind 

 femora, male, 12.75 mm., female, 15 mm. 



Two males, 2 females. Arizona, Dunn (L. Bruner; U.S.N.M. Kiley 

 collection). It was originally described by Thomas from Arizona. Pro- 

 fessor L. Bruuer writes me that he has received the same species from 

 Tepic, Jalisco, Mexico. 



This insect may be instantly distinguished from every other in the 

 entire group of Melanopli by its peculiar blackish punctuation and the 

 annulate antennae. I had an opportunity of studying the type many 

 years ago, and part of the above description is taken from notes made 

 at the time.
