356 M. H. Jekel on new Curculionidous Beetles. 



Spicilegia Entomologica. — II. Descriptions of new Curcu- 

 lionidous Beetles collected on the Voyage of H.M.S. Herald. 

 By M. Henri Jekel^ of Paris. With Notes by Adam White. 



M. Jekel of Pax'is has kindly furnished me with descriptions of 

 four new species of Rhynchophorous Beetles, collected on the 

 voyage of H.M.S. Herald, when commanded by Capt. Hemy 

 Kellett, C.B., who entrusted them to me for description. The 

 grant for the publication of the zoological resvilts of that voyage 

 was exhausted before the Annulosa were reached. The collec- 

 tions were formed chiefly on the Pacific shore of Central America ; 

 a few specimens were brought from more northern parts. I 

 intend to give a list, with brief descriptions, of some of these. 

 Dr. Berthold Seemann, whose fine work on the Botany of the 

 Voyage has given him a great name among modern naturalists, 

 was the chief collector. 



I cannot pretend to give the detailed descriptions of M. Jekel, 

 nor his micrometrical admeasurements, which must often be 

 rather individual than qjecific. The care, however, and the de- 

 tail displayed in the descriptions drawn up by Jekel and Dr. 

 Horsfield are very evident to those who know and have thoroughly 

 studied the subject. But never was the saying truer than in these 

 days of railroad travelling and electric telegraph, " vita brevis, 

 ars longa." The descriptions of Erichson, Germar, and Guerin- 

 Meneville, of all modern entomologists, seem to me to be models, 

 especially for species. — A. W. 



Arrhenodes xantJiozonatus, Jekel. 



A. elongatus, niger, subnitidus, antennis (artic. 4 prim, exc.) tho- 

 raceque opacis ; rostro basi cum capite canaliculatis, dein bifariam 

 crenatis, apice rude punctatis ; thorace pone medium ampliato, 

 angulis anticis spinosis, medio canaliculate, impunctato ; elytris 

 antice scrobiculatis, postice profunda punctatis, interstitiis alternis 

 costatis, fascia lata ochracea pone medium ornatis ; femoribus 

 omnibus tibiisque anticis dentatis. {S) 



Long. tot. 16, rostr. 3^, cap. ly%, thor. 3^, elytr. 7-^q millim. 



Latit. bas. rostr. y'^, bas. cap. 1^, tbor. ap. {-^, pone med. 2-^, 

 bas. 2, elytr. 3, truncat. apic. 1^ mill. {S) 



Allied to, and of the same grouj) as Arrh. lincatus, Sch.* Ros- 

 trum somewhat longer and narrower from the insertion of the 

 antennse to the apex than from that part to the base. Head sub- 



* Arrhenodes lineatus, Sch. (Gen. et Spec. Cure. v. 476). The specimen 

 deseribeil in that work by Gyllenhal is a ? : the S being unknown to him, 

 he couhl not indicate the character bek)nging to that sex, of having the 

 anterior angles of the thorax spinose. One such S specimen may be seen 

 in Mr. Bowring's Collection. No doubt the $ of the above-described spe- 

 cies has the angles of the thorax unarmed, like that of the Arrh. lineatus.
