Species of Rhynchophorous Ooleoptera. 151 



Calvertius, gen. nov. {Hylobudes, Lac). 



Rostrum cylindricum, modice elongatum ; antennae maris fere ad 

 apicem, feminae bene ante medium, insertae ; scapo elongate, 

 clava irregulari, ab articulo octo vix abrupte disereta. Scrobes 

 latse, laterales, anterius superne visibilea, posterius superne 

 occultse. Oculi sat magni, transversi, subtus paulo angustiores. 

 Tibiae anteriores subcompressae, intus minute serratae vel tuber- 

 culatae, ad apicem estus unco curvato armatae. Metasternum 

 modice elongatum. Coxae anteriores parum prominulae, contiguae; 

 presternum anterius minus profunde emarginatum. Coxae inter- 

 mediae distantibus. Femora omnia baud clavata, fere simplices, 

 subtus tubereulo minuto munita. 



This insect is systematically closely allied to Hi/Iobius, 

 though differing in numerous details of minor importance ; 

 the rostrum, however, is more elongate and cylindrical, the 

 antennas are differently inserted in the two sexes, the femora 

 are more linear, and the uncus of the front tibia is placed at 

 the outer angle and is not directed abruptly inwards. In the 

 form of the rostrum and front tibise Calvertius agrees better 

 with Heilipus, but from all the forms of that great but com- 

 posite genus it may be distinguished by the sublinear minutely 

 tuberculate femora, and by the insertion of the antennae being 

 different in the two sexes. 



Calvertius araucarice, sp. n. 



Suboblongus, nodulosus, rufo-niger, antennis nigris ; thorace in- 

 aequali, lateribus plus minusve lobato-dilatatis ; elytris tuberculis 

 rufis fere in seriebus obliquis dispositis. 



Long, absque rostro 15-18 miUim. 



Hah. Chili ; in Araucariam imhricatam ; cujus lignum 

 annosum larva destruit. 



Rostrum 4 or 5 millim. long, cylindrical, dull, much 

 punctured, of a piceous colour ; antennaj inserted in the male 

 very near the tip, in the female about one thii-d of the length 

 behind it ; eyes above rather widely separated, with a small 

 deep canaliculiform fovea between tliem. Thorax with the 

 surface very uneven, constricted near the front, and on each 

 side expanded ; there is a broad, vague, longitudinal impres- 

 sion along the middle near the base, tliis becomes furcate 

 about the middle, and on the middle of the front there is 

 another vague depression ; the elevated parts are irregularly 

 sculptured, almost as if corroded. The elytra are rather
