ochreous) hair : the entire insect is decidedly smaller than (E. arahella, 

 and much more nearly allied to (E. divisella. 



CE. trijugella, Zeller, is Walker's OS. hracteatella. 



(E. griseicostella, Zeller, is certainly Walker's (E. productella : the 

 colouring of the secondaries is very variable, and Walker's "fawn- 

 coloured" stands for half a dozen different tints; in this case it is a 

 dark greyish-brown. 



I believe that the above notes will clear up most, if not all, of the 

 synonyms in connection with this most valuable paper of Professor 

 Zeller' s.

DESCEIPTION OF A NEW SPECIES OP FJENTATOMIBM FEOM 



MADAGASCAE. 



BY W. L. DISTANT. 



The genus Memmia is peculiar to Madagascar, and, like many 

 other genera belonging to that fauna, is a modification of a closely 

 allied African genus. In this case, Memmia is allied to Atelocera, both 

 of these genera having but four-jointed antennae, the second joint of 

 which in Ateloccra is dilated, and in Memmia is simple. 



Two closely allied species have hitherto represented the last 

 named genus ; a third, collected by the Rev. Deans Cowan, is here 

 described ; it can be at once recognised by the great length of the 

 scutellum. 



Memmia Cowaki, n. sp. 

 Head black, coarsely punctate, with a short, central, basal, longitudinal, ochra- 

 ceous fascia ; antennae black, the basal joint Just passing apex of head, second joint 

 much the longest, third joint slightly longer than fourth ; rostrum black, not quite 

 reaching posterior coxae. Pronotum reddish-ochraceous, very coarsely and darkly 

 punctate, the lateral margins and a central longitudinal fascia, pale ochraceous and 

 laevigate ; on the inner-side of lateral margins the punctures are somewhat confluent, 

 thus rendering the colour almost black ; anterior portion of lateral margins deeply 

 crenulate ; remaining portion, including lateral angles, wliich are sub-prominent and 

 rounded, very finely and indistinctly crenulate. Scutellum long, passing the apex 

 of corium, reddish-ochraceous, coarsely and darkly punctate, with an indistinct, 

 central, longitudinal, ochraceous line. Corium reddish-ochi-aceous, coarsely and 

 darkly punctate, with a pale Isevigate spot on posterior portion of disc, and the base 

 of costal margin also pale Isevigate. Membrane small and very pale fuscous. Ab- 

 domen above black ; connexivum pale ochraceous. Body beneath and legs black, 

 abdominal margin pale ochraceous. The under-side of the body is also more or less 

 thickly clothed with ochraceous pubescence, which, on the abdomen, does not out- 

 wardly extend beyond the stigmata, nor inwardly to discal centre. Anterior femora 

 spinous beneath, more prominently so on apical third. 



Long. 17 mm. Exp. pronot. ang., 9^ mm. 



Hab. : Madagascar.
