but not greatly elongate; 8tli joint rather longer than 

 broad 9th scarcely so long as 8th; 10th scarcely stouter 

 than 9th about as long as broad; 11th johit elon-ate 

 about as long as the three preceding joints together, quite 

 twice as long as broad. Head small, with the tubei'cles 

 m front very short, the eyes small. Thorax quite as long 

 as broad, the sides not dilated in the middle, so that it i^ 

 not narrower at the base than in the middle, and is but 

 little narrowed towards the front, the central fovea distinct 

 the lateral ones indistinct. Elytra about one and a half 

 times as long as the thorax, not greatly wider at the

Victoria: sent to me by Henry Edwards, Esq.

Tyrus mutandus, n. sp. Eufescens, antice angustatus, 

 sat dense setosus, impunctatus ; pedibus elongatis ; ely- 

 trorum stria suturali basi foveolato. Long. 1| mm. 



Antennae longer than head and thorax, reddish-yellow, 

 1st and 2nd joints about equally stout; 1st longer than 

 2nd; 2nd about as long as broad; 3, 4, 5 about equal in 

 length, each a little longer than broad ; joints 6, 7, 8 

 slightly shorter than the preceding joints, especially the 

 8th; 9th joint stouter and longer than the 8th, about as 

 long as broad ; 10th joint slightly broader and a little 

 shorter than 9th, not quite so long as broad; 11th joint 

 stout, oval, as long as the two preceding ones, but stouter 

 than they are. Head narrow, not half the width of the 

 elytra, the antennie approximate at their insertion, the 

 tubercles contiguous but separated by a well-marked 

 channel, on each side near the eye is a distinct fovea ; the 

 vertex is elevated, smooth and shining. Thorax longer 

 than broad, only about half as broad as the elytra, much 

 narrowed in front, behind the middle with a very deeply- 

 impressed curved line, which terminates on each side in a 

 deep but ill-defined impression ; it has no punctures, but is 

 clothed with a short upright pubescence. Elytra bright

 a sutural stria which is very deeply impressed at the base, 

 and outside this a short, "deep and broad humeral im-
