OF NEW ZEALAND. 311 



This species in appearance is quite as much allied to the following 

 (Atopida) as it is to the preceding ones ; yet it is with these that its 

 structural characters associate it. The specimens I have seen are in 

 extremely bad condition. 



This species has been sent from Tairua by Captain Broun. 



NOTE. The insect is fragile, difficult to preserve in good order, and 

 is peculiarly susceptible to the attacks of mites. Its elytra, like those of 

 C. inollis, have a more or less spotted appearance. 



558. C- granulatus, n.s. In form this species more nearly 

 resembles the C. punctatus than C. mollis ; it is rather dull, castaneous, 

 with testaceous legs and antennae, and densely clothed with yellowish 

 hairs. Head moderate, labrum quite distinct, yet not greatly exposed, 

 the membraneous space somewhat abbreviated, and its whole surface 

 covered with small granules. Thorax narrower than the elytra, short, 

 the base and apex bisinuated, the sides rounded and not much dilated, 

 its angles obtuse ; sculptured in the same way as the head. Elytra 

 closely but not coarsely punctured and a little rugose. 



Length, 3! lines ; breadth, i. 



I found one example only near Whangarei Heads. 



559. C. medius, n.s. Somewhat similar to C. punctatus ; of a 

 moderately shining chestnut-red, the head and thorax redder than the 

 elytra. 



Antenna elongate, their third joint scarcely half the length of the 

 fourth ; the rest normal. Head moderately large, its middle portion 

 finely and rugosely punctured, the sides finely granulated ; palpi rather 

 stout ; labrum not much exposed ; the usual membraneous space not 

 discernible. 



Prothorax short, its base and apex bisinuated, the sides widened 

 and rounded, with obtuse angles ; the discoidal space is finely and 

 distinctly punctured, the lateral portions more obviously and closely. 

 The elytra are a little wider than the thorax, moderately punctured and 

 slightly rugose, and each bears three very indistinct longitudinal eleva- 

 tions. 



Length, /j.|- lines ; breadth, nearly 2. 



The species is intermediate in structure between the preceding and 

 those belonging to Atopida, so far as the head is concerned, but is 

 likely enough to be mistaken for C. punctatus. It is at once distinguish- 

 able by the abbreviation of the labrum and the absence of the mem- 

 braneous space at its base. 



I found one specimen at Parua, near Whangarei Harbour. 



Atopida. 



White. Sharp; Ann. Mag. Nat. Hist., July, 1878. /. 48. 



The following species are united to form this group, characterized by 

 the characters given below. I believe Atopida castanea, White, will also 

 be referable to it.
