12G ifr. H. W. Bates on the Longirorn 



This genus partakes of tlie characters of Xylotoles and 

 Tetrorea^ and is equally allied to both these genera, which 

 liave been placed by Lacordaire in two widely separated sub- 

 families. 



Psilocnwia linearis, n. sp. 



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

 lateral! fusca, interdum obsoleta, basi sparsim lineatim punctatis, 

 stria suturali fortiter impressa. Long. 2|-8| 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 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, seel facias multo diversa. Cyliudrica, sub- 

 tilissime pubescens. Antennoe graciles, corpore duplo longiores, 

 vix pubescentes ; scapo basi extus gradatim dilatato. Cajmt inter 

 antennis concavum, froute infra paulo angustata. Thorax cylin- 

 dricus. EJijira cyliudrica, basi thorace distincte latiora, humeris 

 fere rectangulis, apice declivia obtuse rotundata, supra prope basin 

 transversim. depressa, stria suturali solum distincta. Pro- et 

 mesosterna angusta, plana. Caetera ut in Stenellipsi. 



Belongs to the same group as Stenelh'psi's, from which it 

 differs in the mesosternum between the coxte being nearly as 

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

 cylindrical ; the metathorax appears somewhat shortened, the 

 distance between the anterior and middle coxa3 being no less 

 than that between the middle and the hind pair. 



Spilotroffia maculafa, n. sp. 



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

 elytris castaneo-fusco maculatis, interdum plaga majore transversa 

 communi poue 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 are very irregular, and lie
