Psilocn^ia, nov. gen. 



Gen. Xylotoli affine, sed corpore lineari, et metasterno haud abbreviate 

 Linearis, subdepressa. Antennas corpore paulo longiores ; articulo primo basi 

 extus subito dilatato, tertio et quarto cseteris multo longioribus. Caput 

 exsertum, inter antennas vix concavum. Thorax fere cylindricus, inermis. 

 Elytra humeris valde obliquis, apiee singulatim rotundata. Prostemum inter 

 coxas ut in Xylotole planum, apice fortiter dilatatum. Acetabula antica extus 

 haud angulata ; intermedia extus clausa. Femora gradatim incrassata. Tibice 

 intermedin extus emarginatse. Ungues divaricati. 



This genus partakes of the character of Xylotoles and Tetrorea, and is 

 equally allied to both these genera, which have been placed by Lacordaire in 

 two widely separated subfamilies.

Psilocnceia linearis, n. sp. 

 P. linearis, pube adpressa cinerea vestita ; elytris plaga utrinque laterali 

 fusca, interdum obsoleta, basi sparsim lineatim punctatis, stria suturali fortiter 

 impressa. Long. 2^ — 3J lin. 



The ground-colour, visible only on portions of the thorax and head and in 

 abraded parts, is of the same coppery brown as prevails in the genus Xylotoles ; 

 the head is of precisely similar form. The transverse impressions of the thorax 

 are only vaguely marked ; the fuscous lateral streak on each elytron is 

 generally varied with grey spots, and is sometimes reduced to a few dark 

 lineated spots, or disappears altogether; the legs and antennae are partly 

 reddish testaceous ; the pubescence of the thorax is somewhat lineated and 

 denser on the sides. 



Auckland. Mr. Lawson has sent home a very large number of specimens. 



Spilotrogia, nov. gen. 

 Gen. Stenellipsi affine, sed facies. multo diversa. Cylindrica, subtilissime 

 pubescens. Antennce graciles, corpore duplo longiores, vix pubescentes; scapo 

 basi extus gradatim dilatato. Caput inter antennas concavum, fronte infra 

 paulo angustata. Thorax cylindricus. Elytra cylindrica, basi thorace distincte 

 latiora, humeris fere rectangulis, apice declivia obtuse rotundata, supra prope 



transversim 



mesostema 



ana. Caetera ut in Stenellipsi. 



Belongs to the same group as Stendlipsis, from which it differs in the 

 mesosternum between the coxae being nearly as narrow as the prostemum, and 

 in the thorax and elytra being cylindrical ; the metathorax appears somewhat 



distance between
