630 STUDIES IN AUSTRALIAN ENTOMOLOGY, NO. XIL, 



represent L. rnfilahris, Casteln., as well as the species to which I 

 have applied that name. From L. snhiridesceiis, Macl., L. 

 loivigatus differs by the prothorax more depressed and punctate 

 near base, lateral border narrower and not bearing a large puncture 

 from which the posterior marginal seta springs at the Vmsal angles. 

 Two specimens ((J9) from Townsville, Queensland, received 

 from Mr. F. P. Dodd, have the prothorax: shorter (9 1-8 x 2-3, 

 apex 1-5, base 1-9 mm.), more strongly rounded on sides; lateral 

 apical sinuosities of elytra weaker; it is perhaps a closely allied 

 species, but I refrain from describing it without more data as to 

 the amount of variety in shape of j^rothorax in L. hevigatus. 



LOXANDRUS AMPLICOLLIS, n.Sp. 



Elliptical-oval, robust. Eyes large, prominent, not distant 

 from buccal fissure beneath; prothorax wide at base, punctate on 

 each side of base; elytra convex, fully crenulate-striate; interstices 

 convex, 3rd unipunctate; lateral apical sinuosities feebly developed. 

 Black, nitid; legs black; tarsi and antenna3 piceous; labrum dark 

 piceous. 



Prothorax wide ('2-.5 x 3-15 mm.), convex, much wider across 

 base (2-65 mm.) than apex (2 mm.); sides strongly rounded; apex 

 emarginate; anterior angles widely bordered ; base truncate ; 

 basal angles rounded; border wide on sides, wider towards base, 

 bearing on edge at basal angles the posterior marginal puncture; 

 median line fine. Length 10-11, breadth 3-9-4 mm. 



Hab. — Q. : Townsville (Dodd), Gulf of Carpentaria (given to 

 me by Mr. French; Coll. Sloane). 



Closely allied to L. rvfilabris, Casteln., but of stouter build; 

 elytra much more convex; the essential difference is in the shape 

 of the prothorax, which is much wider in proportion to the 

 length, more strongly rounded on sides and far wider across base. 

 From L. hevigattis, Macl., it differs by form more convex; pro- 

 thorax more strongly rounded on sides, much wider at base; elytra 

 less strongly sinuate on each side of apex, interstices much more 

 convex. The punctate prothorax separates it from L. quadricoUis, 

 SI.
