PHTLLEEYTHEUEUS.

■ 





Four examples, one of the supposed females (with a comparatively smooth rostrum) 



. 







ving the first ventral segment as deeply excavate as in the male. The much 



narrower stripe on the prothorax and elytra, the more closely punctured prothorax, 



the widely separated punctures of the elytral striae, and the subcarinate pygidium 





distinguish this species from P. circumdatus ; and the extended, differently-placed 



• 



stripe separates it from P. rectistriatus. A closely allied unnamed form with the stripe 



extending along the fifth elytral interstice to the tip, &c, occurs in Ecuador. 



erythrurus annulatllS, sp. n. (Tab. IV. figg. 27, 2 ; 28, 28 a, 6 , var.) 



■ 



Somewhat fusiform, rather broad, opaque above, black, pruinose; the prothorax with a broad, strongly 



ue fascia on each side of the disc (the two fasciae coalescent just behind the apical constriction), and 





■ 



the elytra with a common, transverse, sharply-defined, saddle-shaped annul us, extending from a little

below the base to about one-fourth from the apex and reaching the outer margin, fulvous or ochreous, 



■ 



the large enclosed space on the elytra sometimes fusco-castaueous or brown. Rostrum very stout, feebly 



curved, short, a little more than half the length of the prothorax, closely punctate to near the tip, the

about as long as broad, obliquely narrowed anteriorly, feebly bisinuate at the base, transversely depressed 

 on the disc posteriorly, sparsely, finely punctate. Scutellum elongate-triangular, flattened. Elytra very

Hab. Costa Rica, Cariblanco {Lank ester), Savanillas de Pirris ( Underwood) ; Panama, 



Chiriqui 4000 feet (Champion). 



■ 



Six examples, the four from Costa llica with the space on the elytra enclosed by the

annulus brownish or fusco-castaneous. this portion being black in the two from Panama. 



■ 





The rostrum is as short as in Cactophagus mdeherrimus.

9. Phyllerythrurus circumdatus, sp. n. (Tab. IV. figg. 29, 29 a t 6 .) 



■ 



Somewhat fusiform, opaque above, black, pruinose ; the prothorax with a broad oblique stripe on each side 





extending forward to the subapical constriction, and the elytra with a still broader curved band extending 



down the outer portion from the base to very near the suture beyond the middle (leaving a common, 





elongate, subtriangular patch on the basal half and the apex black), fulvous. Rostrum stout, strongly 

 arcuate, somewhat abruptly bowed at the tip, as long as the prothorax, coarsely and rather closely 

 punctured to about the middle and almost smooth at the apex, the widened basal portion feebly sulcate 



between the points of insertion of the antennae, the apical portion smoother in the 2 > the bilamellate 





peduncle of the submentum very prominent anteriorly, the frontal fovea oblong. Prothorax as long as 

 broad, narrowing from the base, the sides obliquely converging anteriorly, the base bisinuate, the disc 



■ 





transversely depressed posteriorly, very sparsely, finely punctate. Scutellum elongate-triangular, flattened. 

 Elytra obliquely narrowing from the rounded humeri, very finely punctate-striate (the punctures on the 

 fulvous portion indicated by a larger and darker spot), the interstices flat. Pygidium rather convex, 

 sparsely punctured. Beneath very sparsely punctate ; metasternum broadly excavate down the middle 

 from a little below the subconical intercoxal process, the excavation continued along the first ventral 





segment in the <$ the fifth segment foveate at the apex in this sex. Femora with a few short erect 

 hairs beneath. 

 Length 12-13, breadth 4^54. millim. ( rf $ .)
