Notable for the generally coarse character of the puncturation^ 

 which is at its maximum on the prothorax. The striae on the 

 elytra are punctulate, but their punctures are little conspicuous, 

 being not much different in character from those of the general 

 surface. I suspect my two examples are both males, and it is 

 probable that the apical ventral segment in the female is less con- 

 spicuously foveated. 



S. Australia ; near Port Lincoln. 



BARYCISTELA (gen. nov.). 

 Caput breve ; mandibulje apice bitidce ; palporum maxillarium 

 articulus secundus robustus quam tertius duplo longior, 

 apicali longitudine sat a^qualis ; hoc magnus triangulum 

 a^quilaterum formans, labialium forma similis sed minor ; 

 oculi (maris ?) parum approximati ; antennas elongatee sat 

 graciles, articulus 3"^ quam 4'^'' paullo brevior ; prothorax 

 fortiter transversus, quam elytra vix angustior basi sub- 

 bisinuatus ; femora subtus sulco elongato impressa; tibiae 

 anticas apice extus dilatataj ; suturae ventrales apicales 2 

 valde impressed ad latera sat fortiter retro rsum directce ; 

 prosternum inter coxas valde elevatum ; corpus robustum, 

 latum, alatum. 



Agreeing with Homotrysis in the possession of the characters 

 that would entitle to a place in AJhcula, as tabulated by 

 Lacordaire (viz., short bifid mandibles, head free in repose, 

 anterior coxae not contiguous, tarsi lamellated, &c.), this genus 

 differs from Homotrysis (including Hyhrenia and Lisa) by its 

 totally different build, which is very exceptionally robust for the 

 family, recalling somewhat the appearance of Dascilhis : also by 

 the extremely strong and abrupt elevation of the hind part of 

 the prosternum, which is considerably more marked than in 

 Homotrysis tristis, Germ., in the very much longer sulcus running 

 inward from the apex on the underside of the femora, much 

 shorter third joint of the antennae, &c. From Nocar it differs, 

 inter alia, by its much more robust and parallel form, the hind 

 part of the prosternum very much more elevated, kc. ; from 

 Scaletomerus by the last of the characters just named, by greater 

 robustness, very different apical joint of maxillary palpi, prothorax 

 scarcely narrower than the elytra, ikc. ; and from all the above 

 by its anterior tibiae dilated externally at the apex, this latter 

 character approximating the present genus to the Hawaiian 

 Labetis, to which it really bears a good deal of resemblance, 

 though differing in important characters {e.g., the structure of the 

 palpi and femoral sulci). The example before me has lamelhc on 

 the third and fourth joints of the front tarsi and the fourth of 

 the intermediate, l)ut not a well-defined one on the hind tarsi.
