89. Zoniopoda mimicula Rehn. 



Zoniopoda mimicula Rehn, Proc. U. S. Nat. Mus., XXXVI, pp. 132-134, figs. 19, 

 20 (1909). 



Habitat. — Two males, Chapada, Brazil, where they were collected 

 in March and November by H. H. Smith. One of these specimens 

 bears the collector's number, 2108. 



90. Zoniopoda collaris sp. now 



As indicated in the foregoing synoptic table of the species of Zonio- 

 poda, collaris is quite closely related to exilipes Bruner, from which it 

 differs chiefly in the color of the tegmina, the slightly more robust 

 form, and in having the head tinged with red or orange, instead of 

 with pale yellow or dirty white. 



Length of body, cf, 30 mm., of pronotum, 6.25 mm., of tegmina, 

 28.5 mm., of hind femora, 16 mm. 



Habitat. — Chapada, near Cuyaba, Matto Grosso, Brazil, where it 

 was taken by H. H. Smith in January. The type is unique. It is 

 deposited in the collection of the Carnegie Museum. 



I am inclined to believe that this is only a color-variety of Z. exilipes, 

 but keep it separate until we have more material from which to draw 

 conclusions. 



91. Zoniopoda robusta sp. no v. 



A very robust, short-winged insect, in which the color is black, 

 varied with flavous and red. Hind wings with a color-pattern some- 

 what similar to that found in several of the species belonging to the 

 genus Chromacris. 



Head large, smooth; the front perpendicular, viewed in profile a 

 little arcuate, from in front about as broad above as below, moderately 

 high; occiput short, arcuate; vertex very wide, fully three times the 

 width of the frontal costa at the ocellus; the fastigium short and very 

 strongly depressed, its anterior portion sulcate and continuous with 

 that of the frontal costa. Frontal costa only moderately prominent 

 above, its sides nearly parallel save at its lower extremity, where it 

 gradually fades before reaching the base of the clypeus. Eyes small, 

 elliptical, the anterior edge less convex than the posterior, in the male 

 a very little shorter, in the female one-half shorter than that portion 

 of the cheek immediately below them; lateral ocelli large, conspicuous, 

 located in the upper portion of the antennal scrobe just below the 

 lateral carina? of the vertex and in advance of the upper third of the
