Ballophilidae. 



91. Ballophilus australiae, s]>. nov. 



Type.— M. C. Z. 2,168. Queensland: Kuranda 2,000 ft., Sep- 

 tember, 1914 (H.L.Clark). 



Unlike the type-species of Ballophilus, the Liberian H. clavicornis, which is 

 deep violet or almost black in color, the present one is bright ferruginous, in 



life probably more red like various species of Linotaenia, though because of 

 the readiness with which violet is lost in alcohol in various chilopods, this 

 pigment may be present in this species in life. 



Head appearing much like that of a Linotaenia; with no frontal suture. 



Antennae moderate, clavate, the articles beyond the eighth being thickened; 

 geniculate as usual. 



Prebasal plate a little exposed, more on each side of middle than at middle. 



Claws of prehensoral feet not reaching anterior margin of head. All joints 

 unarmed. Basal plate broad, widest anteriorly. Anterior margin of pro- 

 sternum concavely or subangularly excavated. 



Labrum serrate, processes pale, large, somewhat irregular. 



Body constricted a little ways back of the head in the usual manner; from 

 there widening strongly to the posterior third of length and then again strongly 

 attenuated caudad. The anterior region of the body appears extremely 

 slender in comparison with the middle region. 



Dorsal plates crossed longitudinally by many weak sulci between which 

 they are elevated and roughened, and in part somewhat scabrous. 



Ventral pores much more numerous than in B. clavicornis, densely arranged 

 in an elevated, more strongly chitinous, transversely elliptic or oblong area 

 on the posterior portion of plates; present on all plates from the second to the 

 antepenult inclusive. 



All spiracles small, circular. 



Last ventral plate moderately wide, narrowed caudad. 



Coxopleurae of anal legs much thickened; each bearing two pits opening 

 at and lying partly beneath the edge of the ventral plate. Anal legs (male) 

 strongly crassate but not clavate as in B. clavicornis, the proximal articles 

 being thickest. No claw present, this being replaced with a slight mem- 

 branous point. Six articles distad of coxopleura. Densely shortly pilose. 

 Other legs not much differing in different regions of body, all rather slender. 



Anal pores present, minute. 



Pairs of legs, seventy-five. 



Length, 38 mm.
