HYLOBIIDAE. 561 



elevated, slightly porrect shoulders, their sides very gradually expanded 

 and about a third wider behind the posterior femora than the thoracic base, 

 manifestly narrowed but not vertical behind ; their striae are moderately 

 deep but not perceptibly punctured ; third interstices moderateh- elevated 

 from base to apex, each with four spots of scale-like vestiture, fifth very 

 narrow near the base, broader behind the middle but not attaining the apex. 



Legs and antennae normal, club ovate. Eyes rather small and flat, just 

 free from thorax. 



No other species resembles it. The raised and unusually prominent 

 humeral angles form its chief differentiating character. 



Length (rostrum inclusive). 2| mm. ; breadth, 1 mm. 



Mount Algidus. One, found by Mr. T. Hall ; 25th September, 1913. 



4101. Bryocatus lugubris sp. nov. 



Suboblong, entirely black, subopaque, thinly covered with an obscure 

 ashy deposit, and bearing a few dark curled setae along the sides. 



Rostrum thick, as long as thorax, parallel, finely asperate. Eyes small, 

 narrow, just free. Thorax subovate, slightly broader than long, a little 

 wider at the middle than elsewhere ; slightly transversely impressed in 

 front, closely, moderately coarsely, and rugosely punctured, and with a 

 linear impression along the middle. Elytra oblong, rather broader than 

 thorax at the base, twice its length, a good deal narrowed and deflexed 

 behind ; they are subpunctate-striate, interstices rugose, the third and 

 fifth slightly elevated and broader than the others. 



Antennae stout, moderately elongate, club oblong-oval. 



Its nearest ally is B. crassirostris. 



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



Moa Basin ; 20th October, 1913. Another of Mr. T. Hall's discoveries. 



4102. Bryocatus crassirostris sp. nov. 



Oblong, without superficial inequalities, dull fusco-niger, antennae and 

 tarsi black ; covered with nearly circular, depressed, inconspicuous, dark 

 and obscure greyish squamae. 



Rostrum rather shorter than thorax, nearly as broad as the head, 

 parallel, minutely asperate. Eyes flat, quite lateral. Thorax subovate, 

 hardly at all longer than broad, its punctation concealed by the squamae, 

 some of which form a dull greyish streak along the middle in front of the 

 base. Elytra rather broade'r than thorax, about twice its length, slightly 

 incurved at the base, sub vertical and curvedly narrowed behind ; with 

 rather deep but not perceptibly punctured striae ; interstices transversely 

 rugose, the third slightly more elevated than the others and rather 

 thfcker at the base, the second becomes quite linear and does not reach the 



base. 



Antennae short and thick, basal joint of funiculus oblong but thick, 

 club oblong-oval. Terminal joint of the tarsi extending but little beyond 

 the broad divergent lobes of the third, the claws very small. 



Smaller than B. lugubris, its rostrum shorter and broader ; antennae 

 shorter, funiculus with broader joints ; thorax without any central groove ; 

 second elytral interstices abbreviated and narrowed. 



Length (rostrum inclusive). If mm. ; breadth, nearly f mm. 



Hunter Mountains, south-west Otago. A solitary specimen, found by 

 Mr. A. Philpott, at a height of about 6,000 ft., on the 27th December, 1914.
