24 Mr. F. P. Pascoe on some neiv or little-Tcnown 



body in the male (probably shorter in the female), the basal joint 

 scarcely thickened, the second short, the third to the seventh of nearly 

 equal length, subcylindrical, not nodose at the ends, and the remainder 

 a little shorter and somewhat compressed (except the last, which is 

 pointed) ; palpi brownish, the terminal joint of the maxillary securiform, 

 of the labial shortly triangular ; eyes large, reniform ; prothorax rather 

 longer than broad, rounded at the sides, tnmcate and considerably 

 contracted in front, finely punctui'ed, two fovese at the base and an 

 intermediate depression, posterior angle acute ; scutellum triangular ; 

 elytra striate-punctate, much wider than the prothorax, ovate-elon- 

 gate ; body beneath fulvous, pubescent ; prostemum narrow, elevated ; 

 mesosternum V-shaped ; legs short ; tibiae slightly curved, terminating 

 in two short spines ; the two penultimate of the anterior and inter- 

 mediate and the penultimate only of the posterior tarsi lamellate. 

 Length 4 lines. 



DiACALLA [Lagriidse]. 



Caput trigonatum, ad angulum posticum productum. Oculi parvi, rotun- 

 dati. Labium quadratum, membranaceum. Palpi lahiales articulo 

 ultimo subcylindrico. Prothorax late ovatus, antice constrictus. Tihit^ 

 bicalcaratse. 



These characters (and there are also others) are in complete oppo- 

 sition to Lagria, with which genus only — if, perhaps, we except 

 Euomma — in the four which have hitherto composed this family, is 

 it to be assimilated. In other respects it agrees perfectly with the 

 characters of the Lagriidse as laid down by M. Lacordaire, except 

 that the eyes are entire, and the labium is so thin and transparent 

 as to be rather membranous than corneous*. The habit of the 

 species described below is more that of a Titcma than a Lagria. 



Diacalla comata. (PI. IT. fig. 6.) 



D. rufo-fusca, subnitida, hirsuta, fortiter et confertim punctata; abdo- 

 mine infra subrufescente. 



Hah. Queensland. 



Dark reddish brown, subnitid, closely and very coarsely punctured, 

 with short erect greyish and black hairs, mostly arising from the 

 punctures, covering the whole upper surface ; head inclined, trigonal, 

 enlarged behind the eyes, then suddenly contracted into a thick neck ; 

 eyes small, round ; antennae short, the two basal joints slightly thick- 

 ened, the remainder to the tenth gradually diminishing in length but 

 increasing in thickness, the eleventh more slender and as long as the 

 two preceding together ; internal maxillary lobe nan'ow, longer than 



* Fabricius, however, says "labium membranaceum." {E7if. Sysf. i. pars ii. 

 p. 78.)
