THE DFJ'TICIN.E OF NORTH AMEJUCA—CAUDELf.. 



319 



basally and narrowing gradually toward the apex; wings equal to the tegmina in 

 length. Abdomen somewhat compressed; supra-anal plate triangular, deeply and 

 very narrowly divided into two elongate acute lobes ; cerci rather short, the a[)ical 

 portion with two distinct hooks on the internal face; subgenital plate comiiressed, 

 deep, infeiiorly carinate, apical mar- 

 gin .triangularly incised. Anterior 

 femora longer than the pronotum, in- 

 ternal inferior margin with three to 

 four very distinct spines; tibia' with 

 two spines on the external superior 

 margin. Median femora slightly 

 longer than the anteridr, external 

 inferior margin with one or two 

 spines; tibite with two spines on the 

 external superior margin and three 

 internal superior margin. Posterior 

 femora slightly shorter than the head 

 and body, apical half slender and 

 subequal, basal half moderately ex- 

 panded; tibia:' slightly longer than 

 the femora, compressed quadrate in 

 section, regularly spined above, except 

 basally, where the spines are fewer, 

 inferior face with seven pairs of 

 spines and several odd ones, upper 

 inner calcar much exceeding the ex- 

 ternal in size ; posterior tarsi of the 

 type usual in the genus {Dryrnadusa). 

 General color ochraceous buff ( prob- 

 ably greenish in life) , washed with 

 apple-green on the tegmina. Head 

 darker above than below; eyes hazel. 

 Pronotum with an hou?-glass-shaped 



Hgure on the median portion of the disk, and a line along tiie posterior portion of 

 the lateral lobes approximately parallel to the margin blackish-lirown; posterior 

 margin of the disk of the pronotum basally bone-white. Tegmina with a distinct 

 median longitudinal series of subcircular opaque whitish spots, flanked above by a 

 short series not so distinct, a few poorly defined blotches along the anal margin, and 

 an irregular jumbled series in the costal field. 



2[<'asurement><. — Leng'th, l)ody, 29 mm.: })ronotum, O.S; tegmina, 

 il; posterior femora, 24.5; width, pronotum at wide.^t point 5; teg- 

 mina at widest point, 6.5. 



Type. — In the Academy of Natural Sciences, of Phihidelphia. 



Specimens e.ccniiined. — The type (tig. 25), a male from Florence. Pinal 

 Countj^ Arizona, 1903 (C. R. Beiderman). 



Mr. Rehn's statement that the anterior tibia^ have but two dorsal 

 spines on the outer margin is wrong, there being three of them. In 

 the above description the name supraanal plate is used for what 1 call 

 the last abdominal segment. 



The cerci of this species are shaped essentially like those of Capno- 

 hofesfuliginosa (tig. 22), and extend to the tip of the last abdominal 

 segment.
