CUYl'TOUUYNCHIDAK. 239 



liell llt)ck, near Methven. Four exauiples obtained from leaf-mould 

 on the 15th September, 1912, by Mr. T. Hall. 



None of the northern species resemble it, and, though differing 

 greatly in appeararice, it should be located near A. confusus. 



3637. Acalles ignotus sp. nov. 



Compact, convex, rather elongate, attenuated towards both ex- 

 tremities, without conspicuous crests or inequalities, ojiaque; thickly 

 covered with depressed, oviform, principally light-brown squamae, but 

 Avith paler ones Iceland; on the suture, from the summit of the j^osterior 

 declivity to the apex, overlapping grey scales form a pair of contiguous 

 streaks, and a single one on each elytron near the side; antennae and 

 tarsi fusco-rufous, rostrum dark red. 



Rostrum moderately arched, nearly as broad as the head, gently 

 narrowed towards the centre, of nearly the same length as the thorax; 

 feebly carinate along the middle, distinctly and closely punctate in front, 

 squamose behind. Head short, globose underneath. Eyes quite lateral, 

 snbrotundate, only obtusely pointed. Thorax very little broader than 

 long, gradually narrowed towards the front, obsoletely constricted thei-e; 

 its punctation invisible, the apical scales are erect, and a pair of small 

 dark spots may be seen near each side. Elytra almost double the length 

 of the thorax, of the same Avidth as it is, and closely adapted to it at 

 the base, they are gradually narrowed posteriorly, and the declivity is 

 curved ; their sculpture seems to consist of rather distant serial punc- 

 tures. 



Legs robust, thickly clothed with variegated scales; femora elongate, 

 deeply grooved underneath; tarsi rather narrow, Avith slender yellow 

 setae above and below, their 3rd joint moderately expanded and bilobed. 



Antennae finely setose; scape gradually incrassate, medially in- 

 serted, hardly reaching the eye; funiculus more elongate, its basal 

 joint stouter and rather longer than the next, neither very elongate, 

 3rd and ith slightly longer than broad, joints 5-7 short, successively- 

 dilated so that the last is as broad as the base of the club, which is sub- 

 oblong and triarticulate, its basal joint quite half of the entire length. 



Underside densely covered with tawny or fuscous scales. Pectoral 

 cjinal profound, with strongly rounded elevated boi'ders between the 

 middle coxae. Metasternum sliort and medially depressed. Abdomen 

 elongate, distinctly and closely punctured; basal segment obtusely 

 angulate m front, broadly depressed, very large; 2nd segment 

 apparently no longer than the moderately developed 3rd or 4th, but 

 Avitliout any well-marked frontal siiture; 5th as long as the preceding 

 two combined. 



In general form and structure this approaches Xenacalles triangu- 

 lat'us, 1427, but tlie absence of the scutellum excludes it from that genus, 



Length (rostrum exclusive), 3 mm.; breadth, H nun. 



Rakaia Gorge. Described from two examples found by Mr. T. Hall 

 amongst dead leaves on the giound in June, 1912. Anotlier specimen 

 found recently is darker. 



3638. Tychanus squamosus sp. nov. Tychanus Pascoe, Man. N.Z 



Coleopt., p. 498. 



Subovate, convex, opacpie ; thickly covered with depressed and sub- 

 erect squamae, those near the sides and hinder part are jiiceo-fuscous, 

 the others are fusco-testaceous, they ovei-lap one another and occupy 

 9~-Bull. No. 1.
