side at about the apical fourth, and crosses the suture just 

 beyond the middle. One small specimen (possibly immature "> 

 is of a rather dull red. with the part between the zigzag fasciae 

 (these unusually pale) almost black, so that the elytra are 

 tricolourous. 



Orchesia kryophila, n.sp. 



Flavous or fusco-flavous, under surface more or less infus- 

 cated, pronotum with an infuscate (usually semi-double) diseal 

 blotch; elytra with three infuscate zigzag fasciae. Clothed 

 with extremely short pubescence. Length, 3-4 mm. 



Hab. — Tasmania: Mount "Wellington. Hobart, in moss (A. 

 M. Lea). 



Structurally very close to the preceding species, but elytra 

 with dark markings on a pale background, instead of vice 

 versa. Four specimens were obtained from moss on three occa- 

 sions. The head is more or less deeply infuscated, on one spe- 

 cimen being almost black. Of the elytral fasciae the first is 

 sub-basal and touches the sides at the apical fourth, it has 

 several dark extensions towards the base, so that it appears to 

 mark off from six to ten longitudinal flavous spots; the second 

 is submedian and, commencing from the suture, extends oblique- 

 ly forwards, then backwards, and from about the middle of the 

 backward part there is a short spur connected with a suddenly 

 and widely dilated lateral portion; the third fascia is at about 

 the apical fourth, is less sharply defined than the others, and 

 from the suture has a backward trend; between it and the 

 median fascia, on some specimens, the flavous portion appears 

 as six elongate, partially disconnected spots; the suture is pale, 

 except close to the base. From some directions the elytra ap- 

 pear to be rather conspicuously striated, but there are no true 

 striae, although there is a shallow longitudinal depression on 

 each side of the suture. 



Orchesia medioflava, n.sp. 



Dark piceous-brown, tip of prothorax, muzzle, antennae (base 

 paler ) , legs and parts of under surface of a rather dingy cas- 

 taneous, palpi and median portion of elytra flavous. Clothed 

 with extremely short pubescence. Length, 4J mm.
