196 MEMOIBS OF THE QUEENSLAND MUSEUM. 



The prothorax is about as long as wide in the male, but slightly transverse 

 in the female ; in my table, therefore, it could not be associated with any of the 

 species of EEE, but it is a rather shorter and more compact one than any of 

 those there noted, and the dark part of the elytra is confined to the scutellar 

 region; on each elytron it extends across three rows of punctures at the base, 

 and across two where it terminates at the basal third ; in general appearance it 

 is like some small forms of 31. variipennis, and of TrichaUis ampliatus. Parts of 

 the head, and on one male parts of three basal joints of antennse, are obscurely 

 diluted with red. 



METRIORRHYNCHUS APICIVARIUS sp. nov. 



^ Prothorax, scutellum, and elytra (except extreme tips) brick-red, else- 

 ' where black. 



Head with very short rostrum. Antennoe with third to tenth joints ramose, 

 and clothed with distinct hairs. Prothorax moderately transverse ; conspicuously 

 seven-areolate ; front obtusely produced in middle, front angles widely obtuse, 

 hind ones almost rectangular, base very little wider than apex. Elytra thin; 

 with regular double rows of punctures, alternate interstices slightly elevated. 

 Length ( (?9 ), 8-10 mm. 



9 Differs in having shorter and strongly serrated antennae, and subapical 

 segment of abdomen not notched. 



Hah. — Northern Queensland (H. J. Carter from H. Hacker) ; Cairns 

 (E. Allen, A. P. Dodd, and Hacker) ; Gordonvale in July (E. Jarvis). — Type, 

 I. 12275 in South Australian Museum ; cotype, C/2288 in Queensland Museum. 



The ramus of the third joint is more than twice as long as its support, 

 on some of the others it is almost four times as long as its support; the eleventh 

 joint is more than twice as long as the non-ramose portion of the tenth. Three 

 males and one female have the elytra as described, but on two males the elytra 

 are entirely red; these two also have the central areolet deeply infuscated (almost 

 black) ; one of the males with black tips has the mesosternum, trochanters, and 

 front and middle coxoe flavous. From M. trichocerus (which has very similar 

 antenna?) it differs in being more brick-red than flavous, and the elytra entirely 

 pale or with only the extreme tips dark. The difference in the tips of the 

 elytra would distribute the specimens in my table as follows : — Those with the 

 tips black with M. gracilis, from the description of which they differ in having . 

 much longer antennal rami, all of these being much longer than their supporting 

 joints; those with the elytra entirely pale with M. miniatus, from which they 

 differ in having the central areolet much shorter, and the rami much longer. 



TRICHALUS GRIFFITHI Lea. 



On specimens of this species the black apical portion of the elytra varies 

 from one-sixth to more than one-third in length.
