62 COLEOPTERA 



The same author in his paper on " New Zealand Carabidse" (Ann. 

 Mag. Nat. Hist., March-April, 1874) states: "White's description 

 omits all the essential characters of this curious Carabid, and is so 

 vague that there are no means of identifying it without reference to the 

 type. I have seen a specimen so named (Actenonyx bembidioides ) in 

 the British Museum, which quite agrees with Sphallax peryphoides. The 

 extraordinary form of the ligula, and other characters, necessitate the 

 formation of a new sub-family for the insect, which will range near the 

 Odacanthina" 



Wakefieldia. 



Nov. gen. 



Mentum emarginated, without tooth, rather short. Ligula promi- 

 nent, dilated, and truncated in front. Labrum prominent, narrowed at 

 base, sub-truncate at apex. Maxillary palpi rather long and robust, the 

 second joint elongate and thick ; penultimate short, slender at base ; 

 the apical long, oval, and acuminated ; last joint of the labial flattened, 

 very broad, obliquely produced at apex, and apparently ciliated. An- 

 tenna shorter than the body, their basal joint stout, cylindrical, about as 

 long as third; second short; fourth a little shorter than third; joints 

 4-11, oblong and depressed. 



Head as long as, but narrower than, the thorax, with a quadrate 

 muzzle, greatly rounded behind, and united to the thorax by a neck less 

 than half the width of the middle of the head ; eyes moderately large 

 and prominent, distinctly facetted ; mandibles broad, not elongate, 

 arched externally, and pointed at the extremity. 



Prothorax small, cordate, base truncate, apex a little emarginate ; it 

 is dilated and angulated laterally in front of the middle, rounded 

 abruptly in front without front angles, considerably but more gradually 

 narrowed posteriorly ; it is a little convex, margined apically and later- 

 ally, and connected with the hind-body by means of a peduncle. 

 Scutellum elongate-triangular. Elytra large, about twice as long as 

 thorax, sub-oblong, a little rounded, margined along the sides and base, 

 sub-depressed, nearly truncate at apex. 



Legs moderate ; femora a little dilated ; tibia straight and slender ; 

 tarsi elongate, sub-linear, the two basal joints of the two hind pairs 

 elongate, fourth short ; the anterior tarsus of the male scarcely dilated, 

 the two first joints oblong, the basal the stouter, the second slightly 

 narrowed at base, third shorter than second, fourth short, not per- 

 ceptibly hollowed ; claws simple. Front and middle coxa but little 

 separate ; the prosternum elevated and narrow between the coxae. 



121. W. vittata, n.s. Shining, head and thorax black; elytra 

 testaceous, with a broad, irregular stripe on each, widest behind, pitchy- 

 brown ; legs bright testaceous-yellow ; antennae reddish-testaceous, with 

 the basal joint piceous ; palpi fuscous but yellowish at the extremity. 

 Head excessively finely sculptured, so as to be a little dull ; epistome 

 smooth and shining ; it is nearly plane above, but slightly elevated in
