550 (174) Mr. G. R. Crotch's Revision of 



Rhynchothonius. 



g. n. {ti/p. albidoguttatus, Crotch). 



The single species of this 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 coxae being approximated), the thorax wider than the elytx'a 

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



Rhynchothonius albidoguttatus, 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. 



Priotelus. 



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



I think this genus 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. 



Priotelus octomaculatus. 



Erotylus 8-maculatus, Oliv. E. M. vi. 436 (1791). 



Priotelus ■ , Lac. Erot. 500. 



Cayenne. 



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

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

 stria along it. 



Priotelus Dejeani.* 



Priotelus Bejeanii, Lac. Erot. 501. 

 Cayenne. 



Very close to P. 8-maculatus, differs by the black head, and 

 the spots on the elytra more or less connected.
