2i8 RHAPHIDORRHYNCHUS CONSANGUINEUS. 



striato-fortiter punctatis, prope marginem lateralem et ter- 

 tium apicale punctato-sulcatis , singulo elytro lineis 6 — 8 

 punctis 2 ferrugineis notato ; metasterno apici subfoveolato, 

 abdomine basi convexo , laevi ; metatarso antico fere dimidio 

 longiore articulo sequeute. 



Q. Differt: capite breviore et latiore, fronte foveolata, 

 rostro basi breviore , parte antica filiformi , laevi ; antennis 

 brevibus , articulis basalibus laevibus , prothorace paullo bre- 

 viore , elytris latioribus , pedibus brevioribus. 



Long. cf 13—18, 9 121/2— 18 mill. 



Hab. Venezuela (Merida). 



The 2nd interstice has a spot at the base, a line behind 

 the middle and another shorter one at the apical declivity : 

 these two lines are sometimes united , rarely a very short 

 line is seen towards the middle of this interstice where it 

 is narrower than at the basal and apical third. The S"""! in- 

 terstice is broad, convex, yellow-ferruginous till the middle, 

 thence narrower and without coloured lines ; the 4^^ inter- 

 stice has a basal spot and sometimes a short line or a 

 spot behind the middle, as on the 6^^ interstice; and finally 

 there is, near the lateral margin, a long line in the basal 

 half and another shorter one at the apical declivity. 



This species is very closely allied to and intermediate 

 between R. linearis Senna , R. mexicanus Senna and R. 

 panamensis Senna, but as in the 26 specimens examined 

 I have not seen any transitional form , I consider it as 

 distinct. From R. linearis Senna this new species differs 

 by the 2"d joint of the antennae being slightly longer, by 

 the 2nd interstice of the elytra being narrower than the 

 3rd, and by the apex which is spinous externally; the anterior 

 metatarsus is shorter and the disposition of the ferruginous 

 lines on the elytra is different. If 1 compare a female of R, con- 

 sanguineus with a specimen of the same sex of R. linearis , 

 the differential characteristics are the following : the head 

 is narrower, with the basal^ angles less distinct, the elytra 

 are spinous at the external angles of the apex , the 2nd 

 and 3rd interstices and the disposition of the coloured lines
