On the prothorax there is a consiDicuous median line of white 

 scales, which is sometimes continued on to the scutellum. On 

 the scutellum, however, the scales are sometimes of a rusty- 

 red, and similar scales are sometimes on each side of the pro- 

 thorax at the base. On the head the scales are variable, but 

 appear to be usually paler on the tubercles and middle of 

 the forehead than elsewhere. The abdomen (more especially 

 the three apical segments) is conspicuously striped. 



A specimen belonging to Dr. Ferguson was sent to me 

 as the female. It differs from the others in being smaller 

 (13 mm.), the tubercles on the head much smaller (but still 

 rather large), the rostrum obtusely carinated along middle, 

 the prothorax longer than wide, with tubercles smaller and 

 legs regular. Elytra with humeral tubercles very feeble (no 

 more than a few conjoined granules), the interstices with less- 

 conspicuous granules, the third and seventh noticeably raised 

 posteriorly. The under surface with more noticeable punc- 

 tures and the abdomen very feebly striped. The siDecimen 

 is very muddy, and the elytra are without markings save- 

 for a rusty-red patch on each side of the posterior declivity ; 

 this being almost the sole reason for my belief that Dr. Fer- 

 guson is correct in his identification of the sexes. 



Ethemaia Griffithi, n. sp. 



Black; antennae and tarsi diluted with red. Densely 

 clothed with sooty scales, sometimes variegated with patches 

 of whitish or muddy-brown scales. With setae scattered about,, 

 mostly dark on the upper surface and mostly pale on the 

 under surface and legs. 



Head flat between eyes ; with dense concealed punctures. 

 Eyes briefly ovate, prominent, and entire. Rostrum slightly 

 longer than front tarsi, with three (or more probably five) 

 partially-concealed carinas; wider in male than in female. 

 Scape as long as f unicle ; first joint of funicle stouter and 

 slightly longer than second. Prothorax as long as wide in 

 female, slightly transverse in male ; sides very feebly rounded, 

 base very little wider than apex ; with very large but par- 

 tially-concealed punctures or foveas. Elytra almost twice as 

 wide as prothoi-ax, almost parallel-sided to one-third from 

 apex ; third int-erstice with four tubercles, of which the largest 

 overhangs the posterior declivity, fifth interstice with four, 

 a few feeble ones towards each side ; with rows of large but 

 partially-concealed punctures. Under surface with dense 

 partially-concealed punctures. Length (excluding rostrum), 

 54-6 mm.
