seta or spine detected in tj^je, if present being indistinguishable from other 

 setae. Posterior angles of ninth, eleventh, and thirteenth dorsal plates pro- 

 duced. Coxal pores in single series on last four pairs of coxae. None of 

 coxae armed laterally or ventrally; anal pair armed dorsally with a small 

 spine. Anal legs with two claws; spining weaker than in Lithobius, the ven- 

 tral spines being 0, 1,3, 2, 0, while the dorsals are represented by the formula 

 1, 2, 2, 0, 0. Anal legs of male simply thickened, not bearing any special lobes. 



Genotype. — A. scabrior, sp. nov. 



182. Australobius scabrior, sp. nov. 



Type.— M.C.Z. 2,169. Queensland: Kuranda, September, 1914. 

 (H. L. Clark). 



General color above brown of a purple tinge. The head and first dorsal 

 plate much darker, blackish, the former Ughter in a band along the frontal 

 suture. The anterior legs flavous, the posterior pairs chestnut. 



Antennae short, articles twenty-one on one side, twenty-two on the other. 

 OcelU pale, all large, the single one largest, the upper seriate ones somewhat 

 larger than the lower; 1 + 2, 2. Prosternal teeth small, strongly chitinized, 

 dark, 5 + 5. 



Posterior angles of ninth, eleventh, and thirteenth dorsal plates distinctly 

 but only moderately produced. All tergites strongly margined laterally, the 

 margins high, less strongly so caudally. Plates conspicuously roughened 

 with folds and tubercular elevations, the latter especially strongly developed 

 on the posterior plates. Each plate shows a strong median longitudinal fur- 

 row and on each side of this two or more others, these more or less oblique. 



Coxal pores 3, 5, 5, 4, circular to weakly elliptic. 



Ventral spines of penult legs, 0, 1, 3, 3, 2; dorsal, 0, 0, 3, 1, 0; claws 2.. 

 Dorsal spines of thirteenth legs 0, 0, 3, 2, 1, the tibial spine on the caudal side; 

 of the twelfth, 0, 0, 3, 2, 1. First twelve pairs of legs having tibia armed 

 above with but a single spine, this in all on the anterior side. 



Length, near 12.2 mm. 



183. Australobius loriae (Silvestri). 



Lithobius loriae Silvestri, Ann. Mus. civ. Genova, 1894, 34, p. 623. ^ 



Locality. — New Guinea: Moroka.^ 



The species is referred to Australobius with some doubt as only the 

 female is known, whereas the genotype is a male.
