AMERICAN ORTHOPTERA. 29 



This specimen is doubtfully assigned to this species, as the median 

 tibice possess several spines,* and five spines are present on the ante- 

 rior femora instead of three or four. 



CoceoiioSiiN ignobilis Brunner. 



1895, Cocconotus ignobilis Brunnea, Monogr. der Pseudophyll., p. 210. 



Three specimens; two males, one female; Panama (U.S. N. M.) 



Cocconotus ligiiicolor n. sp. 



Type : female; Machuca, Nicaragua (Acad. Nat. Sci. Phila."). 



Allied to C. cethiops Brunner, but differing in the absence of 

 black on the basal joint of the antennae and on the vertex and pro- 

 notum, in the presence of black on the labrum (which is ferrugine- 

 ous in oethiops), in the presence of four spines (instead of one) on 

 the anterior femora, and in the very narrowly emarginate tip of the 

 subgenital plate. 



Size medium. Vertex with two basal tubercles rather prominent ; eyes globose. 

 Pronotum verruculate, centrally constricted, posterior sulcus distinctly marked ; 

 anterior margin broadly rotundate, posterior subtruncate; lateral lobes longer 

 than high, sub-glabrous, lower margin sinuate, anterior angle rotundate. Teg- 

 rmn a rather long, not quite reaching to the tip of the ovipositor, apex subacumi- 

 nate. Wings as long as the tegmina. Anterior femora bearing four spines on 

 the inferior internal margin, genicular lobes rounded ; anterior tibiae with six or 

 seven spines on the internal and external lower margins, foramina slightly inflated. 

 Median femora bearing three spines on the external inferior margin, internal gen- 

 icular lobe bluntly spiued, external rounded ; tibiae with seven spines on the in- 

 ferior margins, Posterior femora moderately inflated, lower margin with six 

 spines; tibiae as long as femora, basally not spiued. Prosternum with two erect 

 tapering processes; mesosternum rectangulate, the posterior margin centrally 

 emarginate; metasternum anteriorly truncate, posteriorly acuminate, foramina 

 of an inverted T shape. Ovipositor rather long, stout, subfalcate, apex acuminate; 

 subgenital plate triangular, centrally sulcate, apex very narowly emarginate. 



General color broccoli brown, the anterior border of the lateral lobes of the 

 pronotum, the spines on the limbs, the labrum, mandibles (except the base which 

 is the general tint), the base of the clypeus, a narrow median line on the face, and 

 the superior and inferior margins of the basal two-thirds of the ovipositor black. 

 Measurements : 



Length of body (including ovipositor) . 46.5 mm. 



Length of pronotum ..... 6.5 mm. 



Length of tegmina ...... 34.5 mm. 



Width of tegmina 8. mm. 



Length of hind femora ..... 19. mm. 



Length of hind tibiae 19.5 mm. 



Length of ovipositor ..... 18. mm. 



* This character seems unworthy of the importance which Brunner has given it.
