widely scattered short linear granulations; process of the mettizone 

 obtuse ang-ulato, with tlie lip much rounded; a trace of the lateral 

 carina? on the front part of the mctazone and prozone. Tegmina 

 ample with basal and median bands wide, especially on the posterior 

 border, both showing some evidence of })eing mad(\ up of annuli, 

 but well delined; bands of the apex faint and composed of annuli, 

 which are segregated into about four subordinate groups, the basal 

 being much the largest. 



Wings yer}' ample, the width two-thirds of the length with tlie apex 

 attenuate somewhat; fuscous band very broad, being about one-third 

 the length of the wing in width, continued upon the posterior margin 

 nearly to the anal angle. Spur very short, extending less than one- 

 fourth of the way to the base; apex hyaline, without fuscous spots. 

 Posterior femora plain without, on the inner side ])lack with two 

 light bands on the apical half; lower sulcus red with one sul)api<"al 

 fuscous band. Posterior tibial red. 



Length of body, female, 33 mm. ; length of tegmina, M nun. ; length 

 of posterior femora, 15 mm. 



One female. New Mexico, Marsh collection, Bruner collection.

As Saussure sa3's, it is similar to Tr'unerotropls citrina^ but it is 

 easih^ distinguished by its very ample wings, which appear to Ijc wider 

 than the ordinary type of wing in this genus by the whole width of the 

 anterior lobe. The species from Nebraska, referred by Dr. Bruner to 

 Trimerotropis latifasciata., probably belongs here, as the New Mexican 

 female is certainh^ not Tnm&rotrojpis latifasciata. 



TRIMEROTROPIS TOLTECA Saussure. 



GiJdrpoda tolteca Saussure, Rev. et Mag. ZooL, XIII, 1861, i>. 897. — Thomas, 



Acrid, of N. Am., 1873, p. 215.

I have not seen this species, but it appears to fall into this group and 

 to be not verj^ closely related to Trbnerotropis mo7iticola. Its distinct- 

 ness seem sto be assured b}' the fact that the outer half of the wing- 

 is inf uscated. For the sake of completeness I append a translation of 

 of Saussure's description of the species: 



Fuscous gray, rough. Head somewhat prominent, vertex ratlier liroad between 

 the eyes, with the scutellum subiiolygonal, not longer than broad. Lateral foveolae 

 subelongate with the apex rounded. Facial costa broader on the front (female), 

 narrower at the vertex and bifoveolate. Pronotum densely punctate and granulate, 

 with the disk of the prozone (female) furnished with slightly elevated oblique 

 carinae in front of the anterior sulcus. Disk of the metazone rough w'ith tlie lateral 

 carinte somewhat distinct, process acute angular with the margin punctate with !)lack, 

 median carina slight but nevertheless elevated anteriorly near the sulcus (on which 

 account the crest of the pronotum, seen from the side, appears to be trilol)ate). 

 Tegmina extending as far as one-third the length of the posterior til)ia', shorter than 

 in allied species, colored throughout and obsoletely banded. Wings with the apex
