AUSTRALIAN STRONGYLIINiE, tfec. 



Var. A. Larger (10-5 x 3 mm.), with the elytral intervals less 

 convex, and the seriate punctures rather smaller. (Labelled 

 Sydney in Coll. Lea). 



The (5 and 9 types are in my own Coll., the ^, given me by 

 Mr. H. W. Brown, without a locality-label (probably Queens- 

 land), the 9 taken by myself at Tambourine Mountain. It is 

 easily distinguished from S. Mastersi MacL, by its raised elytral 

 intervals and more cylindric form. In this, it superficially re- 

 sembles some species of A7iaxo. Types in the author's Coll. 



Strongylium corrugatum, n.sp. 



Elongate, cylindric, nitid-black, elytra with faint cyaneous 

 reflections, apical joints of antennae opaque black. 



Head finely and densely punctate on epistoma, canthus much 

 larger than in the preceding species {S. cylindripenne)^ eyes large 

 and subcontiguous, the separating 

 lamina very narrow in front, triangu- 

 larly widening behind, with a small 

 fovea and sparse punctures thereon; 

 antennae with basal joints much stouter 

 than in the preceding, joint 3 slightly 

 longer than 4, and tumid at apex, first 

 five joints nitid, 6th joint widest, suc- 

 ceeding joints elongate, 11th elongate- 

 ovate. Prothorax very convex ante- 

 riorly, wider than long, and somewhat 

 rectangular in outline, of same width 

 (2 mm.) as head between the eyes, sub- 

 truncate at base and apex, sides par- 

 allel, anteriorly rounded and depressed, 

 posterior angles rectangular, basal margin thickly folded and 

 sulcate within, the sulcus terminating each way in a fovea, apical 

 margin raised, lateral margins not evident from above; disc 

 apparently laevigate (really microscopically punctate), without 

 medial line Scutellurti equilatero-triangular, punctate. Elytra 

 wider than prothorax at base and about three times as long, 

 sides subparallel anteriorly, slightly widened behind middle,
