Type locality. — Trinidad River. Panama (type) ; Tabernilla, 

 Canal Zone (allotype). 



Tyye and allotype.~C2ii. No. 42821, U. S. N. M. 



Described from two examples, the male (type) collected at Trini- 

 dad River, Panama, May 7, 1911, by August Busck, and the female 

 (allotype) collected at Tabernilla, Canal Zone, July 23, 1907, by the 

 same collector. 



This species is allied to tridentifera Gounelle, but is easily distin- 

 guished from that species by having the three transverse black fas- 

 ciae on the pronotum connected to one another by a median longi- 

 tudinal vitta of the same color.

 and along the base and anterior margin; scutellum and elytra pale 

 yellow, the latter vitreous, with the lateral and sutural margins nar^ 

 rowly brownish black, and with a narrow oblique black fascia on each 

 elytron extending from the humerus obliquely backward to the 

 sutural margin behind the scutellum; beneath pale yellow, the legs 

 slightly more brownish, and the body ornamented with black mark- 

 ings as follows: A narrow fascia along anterior margin of proster-

 rather strongly enlarged toward the apex; joint 1 shining, and 

 coarsely, sparsely punctate, the following joints subopaque, rather 

 densely pubescent, and some of the joints armed with long, erect hairs 

 on inner margin; joint 1 robust and slightly arcuate; joints 2 to 4

 sligthly more robust and feebly enlarged toward apex; fifth joint
