suddenly raised jorocess just in front of and between coxae, 

 flat on top, and slightly notched in middle. Metasternum 

 and basal segment of abdomen conjointly feebly concave in 

 middle. Front ro.nt' separated slightly more than middle 

 pair. Length, 4-4Jt mm. 



$ . Differs in having elytra larger and wider, prester- 

 num simple, basal segment of abdomen gently convex in 

 middle, and the femora not quite so stout.

The prosternal process of the male will readily distin- 

 guish from all previously described species, many of which 

 it strongly resembles. 



On most of the specimens before me the scales are of 

 a uniform muddy-grey, but on two males there are sooty 

 scales forming vermiculate patches on both prothorax and 

 elytra. On several specimens the rostral carina is quite dis- 

 tinct, but on others it is concealed before abrasion, this pro- 

 bably being due to disarrangement of the clothing. Before 

 abrasion the prothorax appears to be covered with ordinary 

 granules, but on abrasion these are seen to be flat, and more 

 or less joined together, with irregular punctures or spaces 

 between, giving the whole a vermiculate appearance. Dr. 

 Ferguson informs me that all the specimens were ''taken after 

 very heavy rain clinging to grass stems in pools of water." 



Mandalotus prosternalis, n. sp. 



d" . Of a dingy-red, tarsi paler. Densely clothed with 

 muddy-grey, feebly-variegatecl scales. With numerous com- 

 paratively long suberect setae. 



Ilostrum. without visible median carina, rather more 

 strongly narrowed to base than usual. Antennae rather short. 

 Prothorax and elytra as described in mesosternalis. Proster- 

 num with a strong conical process projecting backwards from 

 between the coxae; these moderately separated. Length, 3|^ 

 mm.

The only otlier described species having a prosternal pro- 

 cess is the preceding, but in that one the process is in front 

 of instead of behind the coxae, and is also of very different 

 shape. The sculpture of the prothorax and elytra (although 

 not the colour or clothing) is exactly as in mesosternaIit>, 

 but that species has the mesosternum armed. 



Mandalotus metasternalis, n. sp. 

 S . Colour as described in rudis. Densely clothed with 

 sooty-brown, feebly-variegated scales. With stout, more
