median line on the protliorax, and on the same specimen the 

 3cutelluni is densely clothed with white scales, but on the 

 others it is more or less glabrous. On many species of the 

 genus the scutellum is rather densely squamose, but as its 

 clothing is particularly liable to abrasion it is usually better 

 left out of consideration. The rostrum of the female is quite 

 as coarsely sculptured as in the male. 



Tyrt.eosus simulator, Lea. 

 The locality of the type of this species was somewhat 

 doubtful. There are now, however, two specimens before me, 

 sent by Mr. C. French as from Queensland and another sent 

 by Dr. Turner as from Brisbane. The elytral interstices at 

 first appear to be double, this being due to each having a row 

 of large punctures along its middle. 



Tyrt^osus cinerascens. Lea. 

 This species was described as having the punctures of the 

 metasternal episterna not quite continuous ; on the types, in 

 fact, and on several recently-acquired specimens, just behind 

 the triangular projection on each episternum, there is a short 

 impunctate and usually shining space. But in two specimens 

 from Sydney, and on two from Hobart, this space is supplied 

 with punctures. 



Tyrt^osus ichthyosomus, Lea. 



Some specimens from Cape York differ from the types 

 in being smaller (5 mm. only) and with the punctures on 

 each metasternal episternum forming a single row, irregular 

 only on the triangular inner projection. The third and 

 fourth abdominal segments also have each an almost regular 

 single row of punctures across the middle, but on the sides 

 they become irregular. 



Many specimens have tlie prothoracic carina quite con- 

 cealed or extremely feeble; on others it is represented by a 

 short, shining, median space. 



Tyrt.^osus vetustus, Pasc. 

 A common Queensland species, varying in length from 

 4f to Sh mm. The punctures of the metasternal episterna 

 are usually interrupted, but are sometimes continuous 

 througrhout. 



Tyrt^osus pardalis, Pasc. 



From Dr. Gestro I received a specimen, evidently a co- 

 type, from Somerset (the original locality) labelled as pardalis 

 and agreeing with the description except in being slightly 

 smaller. In my table of the genus, pardalis is placed with
