apical tooth more strongly curved outwards. The apical ventral 

 SBijment is moru than half as long as the penultimate ; a shallow 

 channel runs down its middle and its hind margin is slightly 

 emarginate in the middle. 



Northern Teriitory of S. Australia ; collected by Prof. Tate. 



L. RoTHEi, Blackb. 



This species was described by me in the " Transactions of the 

 Royal Society of South Australia," of last year, but I was unable 

 to state from what locality it had emanated. There have lately 

 Ijeen referred to me for determination about half-a-dozen specimens 

 of it taken in the Northern Territory, and no doubt the original 

 type came from the same quarter. Comparing it with the two 

 species described above, I find that the clypeus is somewhat inter- 

 mediate, being less rounded at the sides and more transverse than 

 in L. delicaticla, but more rounded laterally and less transverse 

 than in L. Darwini ; the prothorax a little more transverse than 

 in either and less rounded anteriorly, at its widest very little 

 behind the middle ; the elytra much more evidently costate, the 

 puiicturation throughout closer and the scales less conspicuous, 

 tkc, tkc. I cannot find any sexual distinction among the specimens 

 I have seen of L. Rothei, and believe them all to be females; and 

 was probably mistaken in my conjecture that the original is a male. 

 In all, the apical ventral segment is a little more than half as long 

 as the penultimate, its surface glabrous and almost impunctate, and 

 its hind margin gently and evenly arched.
