margin raised and slightly produced in fbe middle ; liypo- 

 ]n'giun) tridentate, the lateral teeth short, the margin b tween 

 them almost straight except where produced into the long 

 apical spine. Wings iiyaline, nervures blackish. Second 

 recurrent nervure received by the third cubital cell at a 

 distance from the base equal to a little more than one-third 

 of the length of the second transverse cubital nervure.

A variety of the female has the head red. The conti- 

 nciit.d form of this species seems to be 7\ truncatusy Sm., 

 but in that species the clypeus is less convex and more 

 strongly punctured at the apex ; the three spines of the 

 hypopygium are much less developed, the lateral ones being 

 alniDst obsolete, the apical dorsal segment is not produced in 

 the middle of the apical margin, and the abdomen is more 

 closely punctured. I'emales taken at Eaglehawk Necic have 

 the head less punctured than would be expected from 

 Erichson's description, but I think my identification is 

 correct. A female from Hobart has the head red.

This species is also found in the mountainous regions of 

 S.E. Australia. 



Tiie name olivieri has priority, and should be used in 

 priference to hyalinatus. Ericlison gives aptcrusf, Oliv., as 

 the name for the female of his species, but I think that name 

 should apj)ly to the female of variabi/i<, Kirby. This species 

 is very close to apterus, which is so common in S.E. Australia, 

 and may prove to be only a cool-climate form of that species; 

 but I think it is distinct.

This species seems to be confined to Tasmania, where it is 

 quite plentiful. It is represented in Victoria by an allied 

 .species, L. anilitans, Sm. I am not at all sure that I was 

 right in sinking Smith's nanie as a synonym of villosus,
