Hob. Mexico, San Andres Tnxtla, Juquila {Salle), Cerro de Palmas (Hoge); 

 Guatemala {Mus. Brit.), Zapote, San Geronimo {Champion). 



Eleven specimens, five of which are from Zapote. Distinguishable from the 



reddish variety of R. ductus, and from other allied forms, by the conspicuous 



cariniform tubercle on the first ventral segment of the male, a character also to be 

 found in the same sex of R. bicinctus and R. maculifer. 



The vars. a and /3 of JR. deltoides have very similarly marked elytra, but they want 

 the ventral tubercle in the male.

44. Bhodobaenus bicinctus. (Tab. VII. figg. 15, 15 a, 6 .) 



Rhodobanus bicinctus, Chevr. Ann. Soc. Ent. Fr. 1885, p. 282 \ 



cJ . Rostrum a little longer than the prothorax, abruptly deflexed from the broad basal portion, the apical 

 portion compressed and almost smooth ; first ventral segment shallowly depressed down the middle, 

 and usually with a more or less distinct, short, longitudinal plica towards the anterior margin. 



2 • Rostrum with the apical portion longer and smoother, the peduncle of the submentum with a compressed 

 dentiform prominence in front. 



Var. J • The median fascia of the elytra reduced to a common transverse patch (which extends forwards 

 along the suture to the base) and a spot on the outer margin, the apical third black ; first ventral 

 segment with a short plica. — Colombia. 



Sphenophorus deliciosus, Jekel, in Mus. Brit. 



Length 6£-10|, breadth 2^-3% millim. 



Hob. Guatemala, Cerro Zunil, Capetillo, Duefias {Champion) ; Costa Eica {Van 

 Patten), Irazu {Rogers), Rancho Redondo, Volcan de Barba, El Tablazo {Biolley), 

 Carrillo ( Underwood). — Colombia {Mus. Brit. : var.), Rio Magdalena l ; Venezuela 

 {Mus. Brit.).

Near R. ypsilon; ferruginous variegated with black— the black markings on the 



■ 



prothorax condensed into three vittse (which are frequently connected along the basal 

 margin, the marginal one sometimes interrupted and often invisible from above), 



i 









and those on the elytra into two common transverse fasciae (the submedian one 

 sometimes widened inwards and extending up the suture to the base, and sometimes 

 divided into two spots, the subapical one arcuate) and a subhumeral spot; the 



transversely excavate posteriorly, smoother and a little less elongate than 

 in R. ypsilon, without densely pruinose streaks and spots; the pygidium pilose at the 



the rostrum longer and smoother, and less abruptly separated from the head.

The four specimens from Venezuela and the variety from Colombia doubtless belong 

 to the same species; they have a short sharply-defined plica on the first ventral 

 segment in the male. Some of Biolley's Costa Rican examples, from one of which 

 our figure is taken, are labelled as having been found on Labiata?.
