small frontal space. As the basal segment of its abdomen 

 is moderately convex the type is probably a female. 



Decilaus lateralis, n. sp. 



Of a dingy reddish-brown, in parts almost black ; legs and 

 elytra! margins dull-red, antennae paler. Rather densely 

 clothed. 



Head with dense punctures, concealed only on a small 

 medio-frontal space. Eyes separated the width of rostrum at 

 base. Rostrum rather short and wide, sides lightly incurved 

 to middle ; with coarse and dense punctures, partially con- 

 cealed towards base. Antennae much as in suturalis. Pro- 

 thorax moderately transverse, sides strongly rounded, apex 

 more than half the width of base ; with crowded partially- 

 concealed punctures. Elytra subcordate, sides strongly 

 rounded and widest near base, margins shining, near apex 

 strongly thickened, and near base very strongly thickened; 

 with rows of partially-concealed punctures. Mesosternal recep- 

 tacle like one-third of a moderately elevated ring. Abdomen 

 with dense more or less concealed punctures. Femora stout, 

 strongly grooved, and edentate. Length, 2 mm. 



Ilab. — Tasmania: Mount Wellington (type in H. H. D. 

 Griffith's collection). 



Allied to the three preceding species, but with the curious 

 metasternal ridges and polished sides of elytra reaching the 

 maximum. Each ridge slightly dilates from its hind to its 

 front end, but the latter is not triangularly produced inwards; 

 it is gently curved, with the convex side near the elytra (in 

 the preceding species the reverse is the case), and it is rather 

 densely clothed. The m.argins of the elytra are conspicuously 

 polished and thickened, especially at the base, where they 

 appear to be curved backwards so as to be quite distinct when 

 viewed from above. The clothing of the under-surface is 

 peculiar, but probably varies sexually ; the type is almost cer- 

 tainly a male. On the elytra the scales are closely applied to 

 the derm and are ochreous, variegated with white, and with 

 stout suberect ones scattered about; on the prothorax the 

 scales are also ochreous and white, but the latter form three 

 fairly distinct lines. On the under-surface the clothing mostly 

 consists of elongate silvery setae, which are denser and more 

 conspicuous on the metasternum and two basal segments of 

 abdomen than elsewhere. The punctures on the bald portion 

 of the head are very distinct, although not very large. 



Decilaus longirostris, n. sp. 



Of a dingy-red, in places blackish ; antennas of a rather 

 pale-red. Densely clothed with rounded scales, varying from
