only posteriorly. A bdomen large, first segment as long as 

 second and third combined, its apex lightly incurved to 

 middle, second longer than third and fourth combined. Legs 

 of moderate length; femora edentate, lightly 'grooved ; tibiae 

 almost straight; tarsi rather thin, but third joint deeply 

 bilobed . 



This genus should be placed near Decilaus, and the 

 typical species in size and shape is almost exactly like D. 

 acerosus, although differing considerably in sculpture of 

 under-surface and in clothing. The mesosternal receptacle is 

 U-shaped, and at a glance appears similar to that of several 

 species in which it has been described as slightly cavernous, 

 but as the wall at its extreme base is very slight and quite 

 vertical it has been regarded as open. Treating it as such 

 the genus, in an (at present M.S.) table of genera allied to 

 Foropterus, would be associated with Poj-opterinus, whose 

 prothorax and elytra are very different. Treating it as 

 slightly cavernous, it would (in the table referred to) be asso- 

 ciated with Exithioides, whose mesosternal receptacle is con- 

 spicuously raised and vaulted, and whose scutellum and meta- 

 sternal episterna are absent. The sides of the elytra are pro- 

 jected inwards, so as to cut off the front portion of the 

 metasternal episterna, these in consequence appear tear- 

 shaped, or like the upper portion of a note of exclamation ( !) 

 reversed. 



Cardiopterocts variegatus, n. sp. 



Dark-brown, in places black ; antennae and tarsi red. 

 Densely clothed with variegated scales, and with numerous 

 stout, suberect ones, scattered about. 



Head with dense concealed punctures. Rostrum almost 

 the length of prothorax, parallel-sided ; with dense punctures 

 concealed towards base, towards apex smaller, denser, and 

 clearly defined. Scape inserted not much nearer apex than 

 base of rostrum. Prothorax regularly convex; with dense, 

 concealed punctures. Elytra rather more than twice the 

 length of prothorax, and at base but little wider, sides rather 

 strongly and evenly rounded, and widest at about middle ; with 

 rows of more or less concealed punctures. Under-surface with 

 dense, concealed punctures. Length, 3 mm.

The majority of scales on the upper-surface are of a dingy 

 light-brown or fawn colour. On the prothorax there is a large 

 sooty spot, of irregular shape, on each side of the base, and 

 extending to the middle. On the basal half of the elytra the 

 scales are mostly sooty, but there are none about the base itself ; 

 on the apical half there are a few small sooty spots. On the
