This is the first record of the species from New ISIexico, and while the 

 data is vague, it is evident they were taken in northern New Mexico.

 Drymadusa arizonensis n. sp. 



Type: d^ ; Florence, Pinal county, Arizona. 1903. (C. R. Biedcr- 

 man.) Acad. Nat. Sci. Phila. 



This specimen is unquestionably a member of the Palearctic genus 

 Drymadusa, and is closest related to D. limhota Brunner,^ from Asia 

 Minor, but is easily separated by the much smaller size and slenderer 

 tegmina, as well as the more apparent maculations of the same. 



Size rather large; form considerably elongate. Head with the 

 occiput rounded transversely, not elevated sloping gradually to the 

 rather narrow, partially sulcate fastigium, which latter is deflected 

 and touches the frontal process, width of the fastigium less than that 

 of the fu-st antennal joint; eyes wide apart, prominent, subglobose; 

 antenna as long as the tegmina. Pronotum selliform; anterior mar- 

 gin shallowly emarginate, posterior margin broadly and evenly rotun- 

 date; lateral lobes with the inferior margin rather narrowly rounded; 

 posterior sinus very sHght. Tegmina elongate, exceeding the apex of 

 the abdomen by half their length, the greatest width is contained six 

 and a half times in the length, apex obliquely truncato-rotundate, 

 costal expansion regular but not marked, greatest basally and narrowing 

 gradually toward the apex. Wings equal to the tegmina in length. 

 Abdomen somewhat compressed ; supra-anal plate triangvdar, deeply 

 and very narrowly divided into two elongate acute lobes; cerci rather 

 short, the apical portion with two distinct hooks on the internal face; 

 subge'nital plate compressed, deep, inferiorly carinate, apical margin 

 triangularly incised. A nterior femo ra longer than the pronot um,
