174 RIiyNCHOTHOXIUS. 



Ehynchotlionius. 



g. n. {tup. albidoguttatus, Crotch). 



Tlie single species of tliis genus differs from all the genera of 

 this section by the very long and narrow rostrum, the large 

 prominent and oval eyes, the deflexed head, the narrow prosternum 

 (the coxse being approximated), the thorax wider than the elytra 

 at the base, and the short anterior tarsi (joints 1 — 2 equal). 



Rhyncliothonius albidoguttatuSj sp. n. 



Fusco-testaceus, ovatus, postice angustior, subtus rufo-testaceus ; 

 alutaceus, nitidus, obsolete punctatus, elytris punctato-striatis, 

 singulis maculis 2 albidis (1 basali, 1 subapicali). L. 3 lin. 



Amazons (Bates). 



The spots vary slightly in size. 



Priotelns. 



(Hope) Lac. Erot. 493 {tup. 8-maculata, Oliv.). 



I think this gen\is has been strained a little to bring in P. 

 lividus and above all P. jucundus, but short of creating new genera 

 for them there is nothing else to be done. It is distinguished by 

 its slender antennae, and pale colour with darker markings. The 

 males have the pilose dot on the first ventral segment. The 

 elytra are very slightly pilose near the apex. 



A. Elytris postice serratis. 



Priotelns octomaculatus. 



Erotylus S-777.acnlatns, Oliv. E. M. vi. 43G (1701). 



Priotdus , Lac. Erot. 500. 



Cayenne. 



Thorax transverse, base truncate, with a punctate fovea on each 

 side ; elytra with the margin broadly refiexed, with a punctate 

 sti'ia along it. 



Priotelns Bejeani/"" 



Priotelus LJcjeaiiii, Lac. Erot. 501. 

 Cayenne. 



Very close to P. S-macnlaivs, differs by the black head, and 

 the s])ots on the elytra more or loss oonnocted.
