 Volcan de Chiriqui (Champion). 



A large number of examples. The black elytral markings of the male are strongly 

 developed only in Costa Rican specimens — in some the apical half is black, as well as 

 the scutellum and lateral patches ; none of the males from Panama have more than 

 the suture, continued along the sides of the scutellum, and a lateral vitta, dusky. 



The species is allied to S. colombica, Burm. The elytral strise are more deeply 

 impressed than in S. colombica, but less so than in S. castor and its allies ; and there is a 

 further peculiarity in the occurrence of a rudimentary fourth stria between the suture 

 and the humeral callus, which is distinct for some distance from the base between the 

 fourth and fifth striae and in some females extends nearly to the apex. 



A Costa Rican specimen is shown on our Plate. 



III. Striis elytrorum septem inter suturam et callum humeralem. 



15. Strigoderma teapensis. (Tab. XIV. fig. 17.) 



Ovata, testaceo-rufa, subtus viridi-senea, fronte tboraceque viridi-seneis vel runs seneo-tinctis, boc vitta laterali 

 flava intus fusco-marginata, elytris flavo-testaceis vitta laterali interdum nigra; capite creberrime 

 (vertice sparsius) confluenter punctato, clypeo brevi lato, margine mediocriter reflexo ; tborace ante 

 medium rotundato-dilatato, angubs posticis valde obtusis, lateribus nullo modo sinuatis, dorso sequaliter 

 convexo, fortiter (versus latera subconfluenter) punctato, linea dorsali laevi, basi integriter marginato ; 

 scutello fere lsevi ; elytris profunde sequaliter punctato-striatis, interstitiis parum convexis bumerali 

 latiore et confuse punctato, margine in 5 recto simplice. Pygidium aspere arcuato-strigulosum, nitidum,

Long. 7|-8 milbm.
