574 COLEOPTERA 



as long as the second and third conjointly, the latter bilobed; claws 

 divaricate. Anterior and intermediate coxce globose, the former sub- 

 contiguous, the latter not far removed from the front pair. 



This genus is founded for the reception of the Calliprason margina- 

 tum of White, which he had associated with the Stenoderus sinclairi of 

 Westwood ; but the latter belongs to Calliprason. This new form 

 should be placed near Leptachrous ; Stenoderus and Calliprason, having 

 finely facetted eyes, belong to another division of the Cerambydda. 



1003. P. marginatum, White \ Voy. Er. Terrains. Head in 

 front rugosely sculptured, the sides strongly wrinkled, vertex almost 

 smooth, with an impressed dorsal line, and rather densely clothed with 

 yellow hairs. Thorax transversely wrinkled, shining piceous ; with a 

 broad longitudinal line of yellow hairs near each side. Scutellum trian- 

 gular. Elytra with a somewhat flattened disc and abruptly deflexed 

 sides ; their sculpture is peculiar, consisting of punctures and granules, 

 so as to give them a somewhat irregular rugulose aspect, and there are 

 two discoidal indistinct costse on each ; their colour is green, with an 

 obvious orange marginal streak defining the disc. The antennce, and 

 legs are pubescent, pale-rufous ; the scape of the former piceous. Pro- 

 sternum rugose ; metastemum and abdomen finely pubescent. 



Length, 8-9^ lines. 



I found two examples at Tairua, from which the- above description, 

 generic and specific, has been compiled. 



Ambeodontus. 



Body elongate, opaque, pubescent. Head oblong, exserted, nearly 

 plane above, with a rather short muzzle ; eyes large, reniform, coarsely 

 facetted, widely separated above ; palpi elongate, terminated by an 

 elongate subsecuriform joint, obliquely truncated at its apex ; antennce 

 two-thirds the length of the body, filiform, robust, inserted at the emar- 

 gination of the eyes, basal joint stout, second small, third and fourth 

 equal, fifth longest, sixth to eleventh decrease in length. 



Prothorax transversal, feebly sinuated at base and apex, with strong 

 lateral, and two discoidal tubercles. Scutellum curvilinearly triangular. 

 Elytra elongate, parallel, with almost prominent shoulders. Legs mode- 

 rately long, femora very slightly clavate ; the posterior tarsus with its 

 basal joint as long as the next two, obconical, second obconical, third 

 bilobed, fourth elongate, claws simple. 



I do not know the author's name. The above characters are from 

 a specimen in my collection. 



1004. A. (Saperda) tristis, Fabr., Syst. Ent., p. 186. S. 



thorace quadrispinoso, corpore fusco. 



NOTE. The entomological student, I apprehend, will experience 

 difficulty in attempting to identify this species by the description quoted 

 above, I therefore subjoin a short diagnosis which will, I hope, more 

 readily lead to its recognition.
