Pedes picei, auricoiyii, fevior'ibus tibiisiiue subcompressis. Long. 



Corp. 24 lin. ; lat. 7 lin. ? Long. corp. 21 lin. ; lat. 7 lin. 



I am indebted to Mr. Shuckhard for the above insect, and the 



species is most probably the Tctralobus Dumoliiiii of Duj)ont's cabinet. 



The antennae and tarsi of this specimen were in too imperfect a 



state to describe.

This singular insect is described from the rich cabinet of Monsieur 

 Dupont in Paris, and it appears to belong to the same subgenus as 

 Tetr. Sfiucfcfiardi. The same insect I have seen before, and as it was 

 named after Mr. Spence, the celebrated entomologist, I have retained 

 that name. 



Oxynopterus* mucronatus. Elater mucronatus, Olivier. 

 Olivier suspects that this insect is the female figured by Voet 

 (vid. Coleop. tab. 45. fig. 34.) ; it was originally described from the 

 cabinet of the Prince of Orange, and certainly differs from the Fla- 

 bellicornis of Drnry, which Olivier seems to doubt. The following 

 short Latin characters separate it at once from Tctralobus. 



Genus Oxynoptervs, Hope. 

 Caput antice subemarginatum, an tennis J' apicibus flaliellatis ely- 



trisque in utroque sexu acuminatis. Thorax angulis anticis fere 



rotundatis, posticis acutis. Elytra striata et mucronata, pedibus 



veluti in Tetralobo. 



Each joint of all the tarsi is clothed beneath with a row of short 

 golden-coloured plush, as in other species belonging to this genus. 



OxYNOPTERUs AuBOUiNi. Oxyu., Mas, brunneo-cinereus, capite 



fortiter excavato, pariim tomentoso. Thorax emarginatus, post ice 



subsimiatus, antice aurantiis capilUs obsitus, depressus. Scutellum 



rotundaium. Elytra brunneo-cinerea, parum tomentosa. Corpus 



infra nigro-cinereum. Pedes concolores, femoribus libiisque com- 



pressis, tarsisque piceis. Long. corp. 62 lin. ; lat. 23 lin. 



The above species was described by me, during my late residence 



in Paris, from the collection at the Jardin des Plantes. It is named 



in remembrance of the late Professor Audouin, who succeeded to the 



entomological chair held by the celebrated Latreille. The locality 



was not stated ; I believe it, however, to be from the East Indies, 



although I cannot actually specify its real locality. It seems to 



differ considerably from mucronatus of Olivier. 



OxYNOFTERUs CuMiNGii. Oxyn. fusco-flavus, aiitennis ferruginds.
