572 COI.EOPTERA. 



This species is unmistakably distinct from Tylodes and Acalles and 

 probably represents a new genus, but this cannot be determined until the 

 issue of WS'tsman's Gen. Ins., group Cn-^itorhynchidae. 



(J. Length (rostrum exclusive), 3f mm. ; breadth, 2J mm. 



Howard Goldfield. A single specimen, found by Mr. T. Hall on the 

 10th May, 1915. 



4119. Acalles anceps sp. nov. 



Convex, subovate, uneven, opaque ; derm nigrescent, antennae and 

 tarsi pale ferruginous ; thickly covered with small, depressed, tawny and 

 rufo-fuscous squamae, those of the latter colour predominate along the 

 elytral suture and top of posterior decliAaty, the coarser suberect ones are 

 of both colours ; legs with outstanding, pale, coarse setae. 



Rostrum as long as thorax, arched, moderately broad, slightly and 

 gradually narrowed behind the middle, dark red and finely punctate before 

 the antennae, with variegated squamae and a fine median carina beliind 

 them. Thorax rather broader than long, abruptly contracted and indis- 

 tinctly bicristatc in front, the middle of the broader portion with a pair of 

 distinct crests, and in lino with these there is a smaller crest at each side ; 

 it is broadly impressed along the middle, the coarse irregular punetation 

 is much concealed. Scutellum not distinct. Elytra subcordate, broader 

 than thorax at the base, their shoulders oblique and covered with pale 

 upright scales, posterior declivity subvertical but not abruptly contracted, 

 they are fully twice the length of the thorax and much more convex ; their 

 irregularly seriate punctures are partly hidden, third interstices tricristate, 

 but with another crest just below the summit of the declivity, in line with 

 this one there is one on the fifth besides the pair on the dorsum, the sides 

 also are uneven. 



Antennae rather short, finely setose ; scape implanted before the middle, 

 scarcely reaching the eye ; basal joint of the funicule stout, obconical, 

 not as long as the elongate second, third slightly longer than broad, joints 

 4-7 transverse, seventh broadest ; club ovate, triarticulate, its basal joint 

 half of the whole length. 



Underside black, with elongate tawny scales. Rostral canal with 

 elevated borders in line with the back of the middle coxae. Metasternum 

 broadly concave behind. Second ventral segment much shorter than the 

 first, hardly as long as the following two combined, fifth longer, with a 

 distinct fovea at each side. 



If the femora had been distinctly dentate underneath this species would 

 have been placed in Crisius. Two species of Acalles resemble this one : 

 the first, A. bicristiceps (3636), may be at once separated by its very 

 elongate-oval club ; the other, A. nodigerus (3942), is a larger and more 

 brightly coloured insect with nodiform el}i;ral elevations. 



Length (rostrum exclusive), 3^ mm. ; breadth, 2 mm. 



Howard Goldfield, eighteen miles from Glenhope. One, discovered by 

 Mr. T. Hall on the 10th May, 1915. 



4120. Acalles cilicollis sp. nov. 



Convex, subovate, widest near the shoulders, considerably narrowed 

 but not abruptly deflexed behind the posterior femora, opaque ; nigrescent, 

 antennae and tarsi fusco-rufous ; tliickly covered j)rincipally with over- 

 lapping fusco-ferruginous squamae, the sides of thoracic disc densely and 

 coarsely fringed with somewhat testaceous scales, basal half of elytra with 

 a few scattered equally pale ones, and bearing also many erect fuscous setae.
