tions a va,s;ue circular one is visil)lc, it oulil nut. tinwever, 1ie rc-^'arded as a fovea; 

 hut on two males from Parachilna (which otherwise a^ree perfectly with the 

 tvpe) tlicre is a small hut distinct fovea, very (hfferent, however, to the large deep 

 one of the females. 



DITROPIDUS COGNATUS sp. nov. 



(^ Bronzy, labrum conspicuously red. basal half of antennae reddish, the 

 club infuscated or black. Head, under-surface. and legs with whitish pubescence. 



Head shagreened and with fairly dense punctures, more sharply defined on 

 clvpeus than elsewehere : median line rather \-ac:ue. Eves moderately separated. 

 Prothovax at base not twice as wide as the median length, sides on apical half 

 stronglv rounded ; with rather dense and sharply defined, hut not very large 

 punctures in middle, becoming larger, denser, and frequently longitudinally con- 

 fluent on sides. Elytra suboblong. sides evenly narrow^ed from base : with rows of 

 not verv large ]nnictures. becoming larger and set in distinct striae on the sides, 

 interstices with ^ery small and dense punctures or slightly shagreened. Legs 

 rather stout, front ones longer than hind ones. Length {6 ?). 3-3 "5 mm. 



9 Differs in ha\ing the median line of the head more distinct, the pro- 

 thorax shorter, with more evenly rounded sides, elytra less narrowed posteriorly, 

 legs shorter, the front ones no longer than the hind ones and the abdomen with 

 sparser clothing on the basal segment, and the apical one foveate.

The distance between the eves of the male is about equal to the length of the 

 three basal joints of antennae, in the female it is about one-third more ; although 

 there is not a distinct median line on the prothorax the punctures along its middle 

 are sparser and smaller than on the adjacent surface. The shagreening of the 

 elvtra is less conspicuous than on the preceding species, the size is considerably 

 larger, and the prothorax is \\-ithout a hisinnate subbasal impression ; the elytra 

 are longer than in D. quadratipcmiis and their surface sculpture is different, the 

 prothoracic punctures are longer and often confluent on the sides, although not 

 strigose ; 7^. iiidisfiiictus is smaller, narrower at the junction of the prothorax 

 and elvtra. and the former with scarcely visible instead of conspicuous punctures; 

 D. ci>i}(/enifu': is smaller, more distinctly coppery, labrum not conspicuously red. 

 and ])unctures different. 



Var. A female from ^^'illianlstown (J. ^. ^. Tepper) has a decided 

 copperv gloss, approaching purple, on the U])per-surface. and the punctiu"es on 

 the sides of its i)rothorax are smaller, although elongate.
