River) differs in being larger (7i mm.), Avith the darker 

 parts lightly infuscate instead of blackish, 



Trichalus apiciflavus, n. sp. 



9 . Black ; sides of prothorax and apical third of elytra flavous. 



Head highly polished. Antennae extending to middle of elytra ; 

 2nd joint moderately distinct, 3rd-llth all longer than wide, serrate, 

 3rd slightly shorter than 4th. Frothorax transverse, apex feebly 

 notched in middle, posterior angles acute and obliquely produced ; 

 3-areolate, the discal areolet connected with the apex by a short 

 broad carina. Scutelhim tranverse, strongly depressed, apex feebly 

 emarginate. Elytra narrow, sub-parallel, tri- (at base quadri- 

 costate ; the interstices wide, with double rows of regular, large, 

 transverse punctures, with the smaller longitudinal and the transverse 

 ridges of almost equal size ; sutural costa trifurcate towards base, 

 with only the middle arm distinct. 



Length 11 mm. 



ffab. N. S. Wales: Sydney (TF. W. Froggatt). 



Allied to funcreus, from which it can be readily dis- 

 tinguished by the pallid prothoracic margins. The only 

 specimen before me is very dingy, but as it was taken in 

 1889 this is probably due to its age. 



Genus Dumbrellia, n. g. 



Head concave, without a distinct rostrum. Eyes very large. 

 Antennae serrate, second joint moderately distinct. Prothorax 

 rounded in front and projecting over the head (which is almost con- 

 cealed by it). Elytra long and flat, sides sub-parallel ; with fairly 

 large punctures, in rows separated by moderately distinct costae. 

 Legs and palpi much as in Metriorrhynchus. 



I have to propose this genus for two species previously 

 referred by me to Calochromus ; from which genus, how- 

 ever, they are evidently distinct by the partially concealed 

 head, much larger eyes, strong elytral punctures and flat 

 legs. From Metriorrhynchus and Trichalus they are 

 separated by the prothorax not divided into distinct 

 areolets but with deep depressions (much as in Calochromus) 

 and by the much smaller elytral punctures, the costae 

 separating which are not distinctly alternately elevated. 

 In Waterhouse's revision of the Lycides the only genus to 

 which they could possibly be referred is Melampyrus ; but 

 T hesitate to refer them to that genus as its two species
