606 COLEOPTERA 



culo primo bast extus subito dilatato, tertio et quarto cseteris multo longi- 

 oribus. Caput exsertum, inter antennas vix concavum. Thorax fere 

 cylindricus, inermis. Elytra humeris valde obliquis, apice singulatim 

 rotundata. Prosternum inter coxas ut in Xylotoli planum, apice fortiter 

 dilatatum. Acetabula antica extus baud angulata ; intermedia extus 

 clausa. Femora gradatim incrassata. Tibia intermedise extus emargi- 

 natae. 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 Lacor- 

 daire in two widely separated sub-families. 



1061. P. lineariS, Bates; Ann. Mag. Nat. Hist., Aug., 1874. P. 

 linearis, pube adpressa cinerea vestita ; elytris plaga utrinque laterali 

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

 fortiter impressa. 



Long., 21-3! 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 some- 

 times 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. 



NOTE. This is, perhaps, our most common beetle; I found it at 

 Tairua and Whangarei, as well as at Auckland. 



1062. P. brouni (Sharp, MS.), Bates ; Ann. Mag. Nat. Hist., 

 August, 1876. Latior, sublinearis, supra depressa; cinerea, subtus et 

 elytrorum lateribus atro-fuscis ; thorace medio dilatato, elytris apice 

 singulatim subacuminatis. 



Long., 3 lin. 



Tairua, near Auckland (Capt. Broun). 



Rather larger and broader than P. linearis ; the thorax especially 

 differing in being somewhat abruptly dilated in the middle. The elytra 

 are considerably depressed behind the scutellar region, and at the apex 

 are singly subacuminate, or, in other words, briefly and very obliquely 

 truncated from the suture outwards. The upper edge of the dark fus- 

 cous lateral streak is very flexuous, and much darker in colour than the 

 rest of the streak. The antennae are palish-testaceous, speckled with 

 fuscous, and are ciliated beneath. 



Spilotrogia. 



Bates ; Ann. Mag. Nat. Hist., July, 1874. 



Gen. Stenellipsi affine, sed facies multo diversa. Cylindrica, subtilis- 

 sime pubescens. Antenna, graciles, corpore duplo longiores, vix pubes-
