Group Cryptorhynchidae.

p. 488. 



Elongate, medially narrowed, only moderately convex, without crests or 

 elevations, subopaque ; obscure rufo-fuscous, sometimes piceous, antennae 

 paler ; irregularly covered with depressed tawny-grey scales, but with some 

 erect ones on the elytra. 



Kostrum nitid, smooth along the middle, with fine setae and punctures 

 near the sides, squamose at the base ; it is rather shorter than the thorax 

 and only indistinctly narrowed near the middle. Thorax slightlv longer 

 than broad, widest and rounded behind the middle, a good deal but not 

 abruptly narrowed anteriorly, base truncate, apex broadlv rounded ; disc 

 impressed longitudinally behind, my second specimen only flattened there, 

 its punctation rather close and coarse. Elytra a third longer than the 

 thorax, hardly any wider than it is at the base, shouldei-s a little rounded, 

 nowhere broader than the middle of the thorax, their sides nearly straight, 

 considerably narrowed but not at all vertical behind ; with only mode- 

 rately impressed striae, the sutural deeper behind, all are more or less 

 crenate-punctate. 



Scape medially inserted and attaining the eye, gradually incra,s.sate ; 

 funiculus longer, basal joint elongate, gradually thickened, much stouter 

 and rather longer than the next, 3rd and 4th slightly longer than broad, 

 joints 5-7 smaller and nearly equal ; club elongate-oval, densely pubescent, 

 indistinctly articulate. 



Legs rather long and stout, squamose, tibiae uncinate ; tarsi with seti- 

 form vestiture underneath, their basal joint triangular, penrdtimate broadlv 

 lobed. 



Underside fusco-piceous, coarsely punctate and nearly nude : terminal 

 three segments somewhat rufescent and finely setose. Pectoral canal deep, 

 extending to bevond the middle coxae, and with elevated borders there. 

 Metasternum moderate. Basal ventral segment large, truncate between the 

 coxae, flat, medially incurved behind, rather longer than the next, 3rd and 

 4th with deep sutures. 



There are no ocular lobes. Head immersed nearly to the subdepressed, 

 longitudinal eyes. 



The most natural position for this species is near A. contractus, 3318, 

 which, however, is rufescent, with yellowish squamae, oviform elytra, and 

 thicker femora. 



During the process of cleaning much of the coarse squamositv disappears, 

 but the depressed greyish scales on two basal spots on the elvtra and those 

 along the suture remain. 



Length (rostrum exclusive), 2 mm. ; breadth. | mm. 



Longwood Range, Southland. Three individuals secured bv Mr. A. 

 Philpott in January, 1913. 



3772. Acalles bicinctus sp. nov. 



Convex, almost uninterruptedly oviform, subopaque. without distinct 

 crests or inequalities : fuscous, legs and antennae rufo-fuscous, rostrum 

 rufo-piceous ; covered with small, depressed, elongate-oval, somewhat 

 fulvescent squamae ; the thoracic disc more thinly, but with a curved band 

 along each side extending forwards to beyond the middle, and another, 

 similarly curved but shorter, just inside it, composed of slightly longer and 

 more concentrated scales.
