margin raised and slightly produced in the middle ; hypo- 

 pygium tridentate, the lateral teetli short, the margin between 

 them almost straight except where produced into the long 

 apical spine. Wings hyaline, 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. 

 Length 9 mm. 



Ilah. Eaglehawk Neck ; February. Hobart. 

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

 nentiil form of this species seems to be T. truncatus^ 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, tlie lateral ones being 

 ahnost obsolete, tlie apical dorsal segment is not produced in 

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

 closely punctured. Females taken at Eaglehawk Neck 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 tlie head red. 



Hemithynnus olivieri, Erichs. 



Thynnus olivieri, Erichs. Arch. f. Naturges. viii. p. 262 (1842). S $• 

 Thynnus hyalinatus, Westw. Arc. Ent. ii. p. 106 (1844). J ? • 



This species is also found in the mountainous regions of 

 S.E. Australia. 



The name olivieri has priority, and should be used in 

 preference to hyalinatus. Erichson gives apterus, Oliv., as 

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

 should apply to the female of variabilis, 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. anilitatis, Sm. I am not at all sure that I was 

 riyht in sinking Sniith's name as a synonym of villosus,
