chamberlin: myriopoda of the Australian region. 69 



Mandible with sixteen or seventeen lamellae. Of these the first has nine- 

 teen teeth as in E. turucanus, these decreasing less in length proximad than in 

 that species. A median lamella with near forty-two teeth, these proportioned 

 nearly as in E. turxicanus. Inner margin below first lamella entire, not at all 

 serrate. 



Teeth of prosternum and prehensors normal. Distal tooth of femuroid 

 larger than the proximal one, but not proportionately so large as in, e. g., 

 E. labasanus. Teeth of next two joints rounded. Claw with a small rounded 

 tooth in addition to the principal basal angulation. 



Sternite of pregenital segment nearly as in E. labasanus. Coxopleural pores 

 exceedingly numerous, small and minute. 



Sternal impressions strongly furcate, the branches long, the angle obtuse. 



Pairs of legs, forty-nine. 



Length, to 90 mm. 



LITHOBIOMORPHA. 



Henicopidae. 



158. Lamyctes tasmanianus, sp. no v. 



Type.— M. C. Z. 2,152. Tasmania (G. H. Hardy). 



General color above bright chestnut or almost cherry-red. A dusky line 

 along the middorsum and the plates also irregularly bordered with the same. 

 Head dusky back of oceUus on each side and across caudal border. Legs hght 

 brown, the last pairs bright yellow distally. 



Prosternal teeth small, 2 + 2. 



Antennae broken off in t\T3e, one entirely, the other beyond the sixteenth 

 joint. 



Posterior angles of none of the dorsal plates at all produced, the corners 

 rectangular or narrowly rounded. Posterior margin of fourteenth tergite 

 weakly incurved, that of the fifteenth more strongly so. 



Coxal pores small but distinct, 4, 4, 4, 3. 



Claw of female gonopods entire as usual, stout. Basal spines 2+2; short, 

 subcorneal. 



Length, nearly 9 nam. 



Readily distinguished from L.fuhicornis Meinert, which it somewhat 

 resembles, in the more elongate and obviously more slender tarsal 

 joints, in having prosternal teeth 2 -{- 2 instead of 3 + 3, etc. Acces- 

 sory claws much smaller than the principal, not approaching this in 

 size as in L. africana Porat.
