120 Mr. H. W. Bates on the Longicorn 



This genus partakes of the characters of Xylotoles and 

 Tctrorea, and is equally allied to both these genera, which 

 have been placed by Lacordaire in two widely separated sub- 

 families. 



Psilocnceia linearis, n. sp. 



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

 laterali fusca, intevdum obsoleta, basi sparsim lineatim punctatis, 

 stria suturali fortiter impressa. Long. 2|-3| 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 antennas are partly reddish testaceous ; the pu- 

 bescence 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, stib- 

 tilissime pubescens. Antennce graciles, corpore duplo longiores, 

 vix pubescentes ; scapo basi extus gradatim dilatato. Caput inter 

 antennis concavum, fronte infra paulo angustata. Thorax cylin- 

 dricns. Elytra cylindrica, basi thorace distincte latiora, hnmeris 

 fere rectangulis, apice declivia obtuse rotundata, supra prope basin 

 transversim depressa, stria suturali solum distincta. Pro- et 

 mesosterna angusta, plana. Caetera ut hi Stenellipsi. 



Belongs to the same group as Steriellipsis, from which it 

 differs in the mesosternum between the coxre being nearly as 

 narrow as the presternum, and in the thorax and elytra being 

 cylindrical ; the metathorax appears somewhat shortened, the 

 distance between the anterior and middle coxas being no less 

 than that between the middle and the hind pair. 



Spilotrogia maculata, n. sp. 



S. ochraceo-testacea, subnitida, capite thoracisque disco obscurioribus ; 

 elytris castaneo-fusco maculatis, interdum plaga raajore transversa 

 communi pone medium. Long. l|-2 lin. 



The maculation of the elytra is peculiar in this little Longi- 

 corn, as it is the derm and not the pubescence merely which 

 is variegated in colour ; the spots arc very irregular, and lie
