Xuthia maura. 
X, angustior, fusca ; antennis pedibusque ferrugineis. 
Hab. Morty. 
Also very nearly allied to the first species, but considerably nar- 
rower, with the cost on the prothorax and elytra more decided, the 
colour a very dark brown, nearly black, with the antenne and legs 
ferruginous. 
These three forms of Xuthia are much too nearly allied to be con- 
sidered ‘undoubtedly distinct,” but, in the absence of intermediate 
varieties, they are sufficiently marked to deserve a place in our 
catalogues. 
Ez. 
Caput breve, transversum, antice marginatum. Antenne basi tecte, 
10-articulatz, articulo basali incrassato, ceeteris sensim crassioribus, 
ultimo rotundato compresso, Prothorax subquadratus, antice paulo 
sinuatus, Elytra parallela. Tibie subtrigonate, calcarate ; tarsis gra- 
cilibus. Corpus oblongum, subdepressum, levigatum. 
A single minute species, having a strong general resemblance to 
Cerylon, constitutes this genus. Its characters, however, place it 
with the Synchitine, from all the genera of which it differs in its 
ten-jointed antenne, gradually enlarging upwards. For the present 
its affinities must be left in doubt. 
Eba cerylonoides, (Pl. VIII. fig. 7.) 
E. rufo-testaceum, nitidum ; oculis nigris, 
Hab, Saylee. 
Oblong, subdepressed, reddish testaceous, shining; head strongly 
punctured, short, transverse, with a margin which is somewhat re- 
flected anteriorly and hiding the lip; eyes black; antenne 10-jointed, 
slightly covered at the insertion, the basal joint slightly incrassate, the 
remainder to the ninth inclusive shortly obconical and gradually in- 
creasing in breadth, the tenth paler, about equal in length and breadth, 
and slightly pointed; prothorax nearly quadrate, not very closely 
punctured ; scutellum very transverse; elytra as wide as the prothorax, 
strongly seriate-punctate ; body beneath testaceous, shining ; tibize sub- 
trigonate, shortly spurred ; tarsi rather slender. Length 3 line. 
Phormesa prolata. 
Pascoe, huj. op. i. p. 102 (Bitoma).—Batchian. 
The addition of five new species to this genus (Phormesa) brings 
the number up, with those previously published belonging to Mr. 
Wallace’s collections, to eight. The following table will show their 
principal distinctive characters.
