panded. Mesosternum declivous in front, and triangular between the 

 coxae. Metasternum with only a feeble, narrow, longitudinal groove 

 at middle. 



Abdomen beneath sparsely, obsoletely, and irregularly punctate; 

 last segment broadly subtruncate at the tip, with a broad, concave 

 depression at apex, the dorsal plate feebly emarginate at middle, 

 with a broadly rounded lobe on each side. Femora nearly similar 

 in shape, and the posterior pair extending to the anterior margin 

 of third abdominal segment. Tibiae narrow, straight, and subcylin- 

 drical; anterior pair with a distinct sinus; and the posterior pair 

 equal in length to the femora. Tarsi rather strongly expanded. 



Length, 14 mm. ; width, 4 mm. 



Type locality. — Cayamas, Cuba. 



Type.— Csit. No. 28382, U.S.N.M. 



Described from a unique female collected at the type locality 

 March 2, by E. A. Schwarz. 



This species differs from all other known species of the genus 

 in having the lateral spine on the pronotum acute and strongly de- 

 veloped, in which respect it resembles the species of Panjsatls and 

 Estlilogena., but differs from these genera in having the surface 

 densely pubescent, and in various other characters. 



Under this species I am placing temporarily two females, one 

 received from the American Museum of Natural History, collected at 

 Tallaboa, near Ponce, Porto Rico, July 23, 1914, the other one in 

 the United States National Museum, collected at Mayaguez, Porto 

 Rico, on February 27, 1912, by C. W. Hooker. These specimens 

 differ from the type in a number of respects, but these differences 

 do not seem sufficiently distinct to justify one in describing them 

 as new, at least not until more material is available for study. They 

 differ from the type in having the pubescence of a more uniform 

 pale brownish-yellow color, with less cinereous hairs intermixed, 

 the pronotum distinctly wider than long, with the lateral spine not 

 quite so acute, and an obsolete nodule on each side between the 

 lateral spine and apical angle, which indicates a relationship to the 

 genus Proeclui; the metasternum is more vertical in front, and in 

 one of the specimens the tibiae are larger and more flattened. 



ATAXIA UNIFORMIS, new species 



Female. — Elongate, parallel, dark castaneous, moderately clothed 

 with a uniformly colored yellowish-gray pubescence, which does not 

 conceal the punctures, and with rather short semierect dark brown 

 setae arising from the punctures; antennae sparsely pubescent, the 

 joints obsoletely annulate and sparsely ciliate beneath; underside 

 more spareely pubescent than above, with long, slender, erect hairs 

 arising from the punctures, and with numerous small round glabrous 

 spots, causing the surface to have a spotted appearance.
