OF NEW ZEALAND. 807 



greatly narrowed aud constricted anteriorly, its sides and hind 

 angles much rounded. Scutelluvi distinct. Elytra elongate-oblong, 

 narrowed behind. Legs stout ; femora nearly straight below, and 

 not notched at the extremity, swollen above ; tihice gradually ex- 

 panded apically, uncinate ; tarsi moderate, third joint sub-bilobed. 

 Mesosternum short, its suture straight. Metastcrnum moderate, flat 

 and canaliculate. Abdomen rather short, two basal segments largest. 

 Body rather broad, depressed, bald, or nearly so. 



A form near Macroscy talus, but distinguished therefrom by its 

 small orthodox club ; differentiated from Pentarthrum by its form, 

 the structure of the snout, &c. 



The genus is founded on No. 1305, now Bcsorliopahis glahrus. 



Macroscytalus (p. 736). 



1433. M. depressus, n- s. Ferruginous, nitid, tarsi aud 

 antennge dilute, minutely pubescent, depressed. 



Bostrum moderately broad, narrowed behind, moderately finely 

 punctured. Antennoi robust, club long, pubescent. Prothorax longer 

 longer than broad, considerably narrowed and slightly constricted 

 anteriorly, rounded behind the middle, slightly impressed before the 

 scutellum ; its punctation neither very coarse nor close, and rather 

 shallow. Elytra very slightly rounded laterally, broadly depressed 

 behind the base, punctate-striate, the interstices with a row of 

 minute punctures. Legs stout. 



May be easily identified by the broad depression before the 

 middle of the elytra. No. 915 (M. ccneoinceus), though somewhat 

 similarly impressed, is a totally different insect. 



Length, i line ; breadth, nearly |-. 



My specimen, mutilated, was found at Parua. 



Proconus. 



Nov. gen. 



Bostrum obconical, as long and, in front, as broad as the head, 

 broadly impressed anteriorly ; its scrobes oblique. Antenna short 

 and stout ; scape short, gradually thickened ; funiculus 5-articulate, 

 longer than scape, two basal joints obconical, second larger than 

 third ; club ovate, compact, its base not greatly exceeding the fifth 

 joint in breadth. Head exserted, with a broad neck. Eyes small, 

 oviform, distinctly facetted, not prominent. Protliorax considerably 

 narrowed and constricted in front, broadly rounded behind the 

 middle. Scutellum distinct. Elytra elongate-oblong, base truncate, 

 apices rounded. Legs stout ; femora inflated, tibice sub-triangular, 

 with distinct hooks ; tarsi rather short, third joint deeply emargin- 

 ated. Body rather broad, depressed, with a few longish hairs on the 

 front of the thorax, and minute ones on the hind-body. Female 

 incog. 



Should be located near Heteropsis. 



This genus is constituted for Pentarthrum asperirostre, which, 

 therefore, must stand as Proconus asperirostris .
