Guadalajara, Jalisco. August 5 and 10, September 14, 1903. 

 (McClendon.) Fifteen males, eleven females. 



Tuxpan, Jalisco. September 4, 1903. (McClendon.) One male. 



Monterey, Nuevo Leon. One male. 



This species exhibits a great amount of color and coasiderable struc- 

 tural variation. The single individual from Tuxpan is almost solid 

 black in color, but no doubt represents this species, as extreme Guada- 

 lajara specimens have the pronotum and head, aside from the yellow 

 lines and borders which are faintly marked in the Tuxpan individual, 

 solid black. The City of Mexico specimen is much more robust than 

 any of the others examined, and may possibly prove to be a distinct 

 species. This form can readily be distinguished from picticornis 

 (Walker) by the orange instead of crimson antennae. This character 

 may be subject to variation, as most the other color characters of the 

 species are, but nevertheless it holds true in the above series, and in 

 eight specimens of picticornis. Good structural characters exist, 

 however, to separate the two forms. 

 Taeniopoda tamaulipensis n. sp. 



Type : 9 ; Alta Mira, Tamaulipas, Mexico. July 4, 1903. (M. E. 

 Hoag.) Coll. Acad. Nat. Sci. Phila. 



Allied to T. picticornis (Walker), but differing in the higher and 

 slightly more arcuate median carina of the pronotum, the greater 

 interspace between the eyes, and the different coloration 



Size large; form very robust. Head with the occiput inflated, 

 median carina obsolete; fastigium obtuse-angulate with distinct but 

 rather low lateral ridges; frontal costa narrow, strongly constricted 

 and evanescent inferiorly, distinctly sulcate; eye subreniform, some- 

 what prominent, slightly shorter than the infraocular portion of the 

 genee. Pronotum cristate, the prozona exceeding the metazona in 

 length; anterior margin obtuse-angulate, posterior margin acute- 

 angulate; prozona with the median carina arcuate and cut, but not 

 deeply, by three transverse sulci; metazona with the crest bent 

 arcuate and very slightly higher than that of the prozona; metazona 

 with distinct lateral angles but no carinoe ; lateral lobes slightly longer 

 than deep, the inferior margin slightly emarginate anteriorly; surface 

 rugoso-punctate. Tegmina equalling the apex of the abdomen, ante- 

 rior margin arcuate, apex somewhat constricted and very slightly 

 oblique truncate. Wings large, equally as long as the tegmina when 

 in repose; apex slightly falcate. Posterior femora almost equal to 

 the abdomen in length, rather slender. 



General color burnt-sienna, the median carina and posterior margin
