CRYPTORHYNCHIDAE. 647 



Legs with coarse greyish setae, tibiae uncinate, the anterior longest, 

 intermediate with a dentiform projection above the middle and another 

 at the outer extremity. 



Underside nitid, dark fuscous, closely punctured, with coarse depressed 

 grey setae. Mesosternal lamina subquadrate, feebly emarginate in front. 

 Metasternum moderate, with a median depression behind. Basal segment 

 broadly rounded between the widely distant coxae, not double the length 

 of second, slightly sinuate behind, third and fourth together as long as 

 second or fifth. Palpi fully exposed. 



In Oreda the lateral dilatation of the rostrum, behind the middle, almost 

 conceals the scrobes from above. This species resembles M. setigera (865), 

 but is more oviform, with more slender antennae, and can be at once 

 separated by the mesosternal lamina. 



Length (rostrum exclusive), 5J mm. ; breadth, 2| mm. 



Wellington ; 21st August, 1916. My specimen is another of Mr. A. C. 

 O'Connor's discoveries. 



Euacalles gen. nov. 



Scrobes lateral, beginning before the middle and prolonged to the front 

 of the eye. Scape inserted before the middle and attaining the front of 

 the eye, gradually incrassate, glabrous. Funiculus rather longer, second 

 joint slightly longer than the moderately stout first, rather slender, third 

 and fourth rather longer than broad, joints 5-7 shorter and slightly broader. 

 Club elongate, with three small indistinct apical articulations. Ocular 

 lobes and scutellum absent. Femora unarmed, long and thick, grooved 

 underneath. Tarsi with narrow basal joints, the penultimate expanded, 

 excavate above, emarginate at apex, entire underneath ; claws small ; 

 soles setigerous. Pectoral canal profound, its raised hind borders reaching 

 the middle of intermediate coxae. Metasternum very short, so that the 

 middle and hind coxae almost touch each other. Second ventral segment 

 half the length of the basal, their suture feebly sinuate, third and fourth 

 together rather longer than preceding one and as long as the fifth. 



The absence of the scutellum, and the truncate thoracic base, prevent 

 the following species being placed in Sympedins, but the penultimate tarsal 

 joint being entire underneath shows that its true position must be remote 

 from all the Acalles allies. 



4228. Euacalles cristatus sp. nov. 



Convex, compact, subovate, without setae, thickly covered with de- 

 pressed, and suberect squamae ; on the rostrum and thorax they are mostly 

 infuscate or quite black, but between the middle and sides of the latter 

 the suberect scales are tawny or obscurely fulvescent and almost form 

 crests ; the depressed tawny or pale fuscous scales predominate on the 

 elytra, whilst the suberect nigrescent ones form an elongate basal crest on 

 each of the third interstices, a short one on top of the posterior decUvity, 

 and a sutural one near the apex, on the fifth there are three short ones, 

 at the side there are three elongate streaks, the longest between the hind 

 thigh and shoulder, this last bears pale suberect squamae only ; the derm 

 is blackish, the antennae, club inclusive, are fulvescent, the tarsi rather 

 darker. 



Rostrum moderately broad, subparallel, equalling the thorax in length, 

 slightly arched, nearly nude, rufescent, and finely punctate in front.
