PsiLOCNiEiA, nov. gen. 



Gen. XylotoU affine, sed corpore lineari, et metasterno hand abbreviate. 

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

 extus subito dilatato, tertio et quarto cceteris multo longioribus. Ca2)ut 

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

 Elytra liiimeris valde obliquis, apice singulatim rotundata. Frostemttm inter 

 coxaa ut in Xylotole planum, apice fortiter dilatatum. Acetahula antica extus 

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

 intermedise 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. 



Fsilocnceia linearis^ n. sp. 



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

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

 impressa. Long. 2 J — 3 J liu. 



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 divei'sa. Cyluidrica, 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 distinct© 

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

 basin transversim depressa, stria suturali solum distincta. Fro- et mesosterna 

 angusta, plana. Csetera ut in Stenellipsi. 



Belongs to tlio same group as Stendlipsisj from which it differs in the 

 raesosternum between the coxa? being nearly as narrow as the prosternum, and 

 in the thorax and elytra being cylindrical ; the mctathorax appeai-s somewhat 

 shortened, the distance between the anterior and middle coxa3 being no less 

 than that between the middle and the hind pair. 



Spilotrogia iiuiculata, n. sp. 

 S. ochracco-testacca, subnitida, capitc thoracisque disco obscurioribus ;
