shoulder and on the third interstice, that on the shoulder is 

 more advanced than the other, but is no larger ; each projection 

 has numerous granules, and these are so disposed as to be 

 suggestive of the suckers on the arms of an octopus. The 

 suture could hardly be regarded as produced at the base. 



Mythites frater, n. sp. 

 <3 . Black ; upper surface with very short, spare black 

 setae : the depressed spaces with indistinct brownish pubes- 

 cence. A ridge of black setae or hair extending from apex of 

 abdomen to between middle coxae, where it is densest. Legs 

 with black setae 



Head with three deep and wide grooves. Rostrum 

 separated from head by a strong transverse impression, with 

 a deep median channel, each side of base with a short con- 

 tinuation of the lateral groove of head. Prothorar about as 

 long as wide ; with large, irregular elevations and deep im- 

 pressions. Elytra at base about the width of prothorax, 

 somewhat wider about middle ; with irregular rows of large 

 punctures, becoming very large at sides ; second interstice with 

 a distinct tubercle just below summit of posterior declivity ; 

 third with a carinated ridge on basal third or two-fifths, the 

 ridge projecting on to elytra at base, behind the ridge, with 

 two or three distinct tubercles, of which the apical one is 

 usually close to the one on second interstice ; fifth and seventh 

 interstices with some smaller tubercles ; shoulders strongly pro- 

 jecting on to prothorax, a laterally-projecting subhumeral 

 tubercle on each side. Front tibiae inflated at apex. Length 

 (excluding rostrum), 13J-18 mm. 



Q • Differs in being larger, elytra wider, apex with two 

 conjoined mucros, third interstice less produced at base ; under- 

 surface without the ridge of hair ; and front tibiae simple.

I have seen in some collections as Eaomus basal is, Boi., 

 and Mythites sulci coll is, Germ. ; but the sutural and third 

 interstices not becoming conjoined at the base readily dis- 

 tinguishes from the species I have identified as basal is, 

 although at a glance the two species appear to be identical ; 

 whilst sulcicollis has the prothorax densely granulate, and 

 usually with a single pronounced median channel. From the 

 description of perfossus it differs in being considerably larger 

 (the smallest specimen is 6 J instead of 4 \ German lines), with 

 the basal joint of the funicle longer than wide (Germar de- 

 scribes the funicle as having all of its joints transverse), as 

 well as in the sculpture of both prothorax and elytra. Begener 

 is described as having only a single depressed carina in 

 front.
