CYMATODERA LONGULA, new species. 



Elongate, feebly shining, clothed with long coarse hairs ; brown to 

 piceous; antennae dark ferrugineous ; labrum, tarsi, a narrow irreg- 

 ular median fascia and abdomen yellow. Head with front coarsely, 

 densely punctate, vertex a little finer, occiput granulate; eyes feebly 

 prominent; antennae slightly longer than head and thorax, joints 

 two to ten subequal in length, joints five to ten feebly serrate, 

 eleventh joint one- third longer than the tenth. Pro thorax twice as 

 long as wide, very feebly constricted both in front and behind the 

 middle, base as wide as apex; ante-scutellar impression small but 

 distinct with a feeble tubercle each side; surface very coarsely and 

 densely punctate. Elytra nearly twice as wide as the throax at base; 

 humeri distinct; sides subparallel, very feebly divergent posteriorly, 

 apices conjointly rounded; punctures coarse, deep, closely placed 

 becoming finer and somewhat confused at apex; intervals flat, with 

 an irregular row of moderate punctures, wider than the punctures 

 near suture, narrower at the sides. Body beneath sparsely pubes- 

 cent; metasternum very coarsely, sparcely punctate, the pubescence 

 very long, recumbent; abdomen coarsely, moderately sparsely, not 

 deeply punctate, second, third, and fourth ventral segments very 

 finely and densely punctate. Legs sparsely but conspicuously 

 clothed with long, coarse hairs. Length, 8-9 mm. 



Male. — Fifth ventral segment deeply, broadly emarginate; sixth 

 ventral wider and subequal in length to last dorsal, sides nearly 

 straight, strongly narrowing to apex which is obtusely rounded with 

 a small, deep emargination at middle; last dorsal truncate at apex, 

 the angles rounded. 



Female. — Unknown. 



Type locality. — Catalina Springs, Arizona. 



Type and paratype.— Cat. No. 23124, U.S.N.M. 



Described from two males. The type from Catalina Springs 

 (Gibbon's ranch, 13 miles northeast of Tucson, 2,800 feet altitude), 

 Arizona, April 10, 1898 (Hubbard and Schwarz) ; the paratype from 

 Santa Rita Mountains (Madera Canon, 4,000-4,500 feet altitude), 

 Arizona, June 8, 1898 (Hubbard and Schwarz). 



The form is nearly that of belfragei. The distinctly granulate 

 occiput, the prothorax equal at base and apex and the abdominal 

 sexual characters of the male make this an easily recognizable species. 

 In the type the suture is narrowly of a paler color than the general 

 color ; the base narrowly and irregularly, the apex rather obscurely, 

 and the flanks before the fascia from the fifth stria to margin also some- 

 what pale. The paratype is similar to the type in all respects except 

 that the entire side before the fascia is not paler than the general 

 tone, the pale color being confined to the sixth, seventh, and eighth 

 intervals.
