532 FAUNA HAWAIIENSIS 



(30) Acrittis Jlavitarsis, Lewis. 



Aeleies flavitarsis Lewis, Ent. Mo. Mag. xvi. p. 79. 



Plate XV. fig. 28. 



I have examined one of the original specimens found by Mr Blackburn. Mr Perkins 

 has not obtained this species. A. fiavitarsis is very clearly distinguished from the other 

 very small species. A. snbrotitndus and A. parvu/us. Its form is oblong and narrow. 

 The prosternum (PL XV. fig. 29) is as short as that of A. subrotundus, but has its base 

 narrow, only about ^ as broad as its front margin between the striae: in front it is 

 medially elevated and rather strongly arched. Meso- and metasterna and first abdominal 

 segment decidedly flattened (the former not impressed), the two latter with extremely 

 fine, very rare, punctures. Suture between the meso- and metasterna distinct. A 

 beaded border, formed by a row of fine impressions, is present along the inner sides of 

 the prosternal striae, and along the lateral mesosternal marginal striae. It is continued, 

 much more sharply marked, along the diverging striae on the metasternum and first 

 abdominal segment. The upper surface has extremely fine rare punctures. Legs rather 

 long. Colour of specimen examined testaceous, length just over | mm. Wings not 

 e.xamined. 



Hab. Oahu, specimen examined recorded from near Honolulu (Blackburn). (Two 

 specimens in the British Museum obtained by Blackburn, placed as this species, belong 

 to A. subrotundus q. v.) 



(31) Aci-ifus so/itarius, sp. (?) nov. 



Laevis, nitidus, supra impunctatus ; prosterno curto, ei A. flavitarsis sat simili ; 

 mesosterno impresso; metasterno in medio sat crebre punctulato. Long, circa i mm. 



There is a single specimen having the keel of its prosternum short, with rather 

 narrow base, and striae widely diverging in front. In this respect the specimen comes 

 close to A. Jiaz'iiai'sis, but is decidedly larger, relatively broader, and with only faintly 

 marked beaded borders. I have given it a name, though it is uncertain whether it may 

 not prove to be a large variety of A. flavitarsis. 



The metasternum is distinctly punctured, the punctures in the middle being rather 

 close and forming a conspicuous group. Wings not examined. 



Hab. Oahu, back of Tantalus, vi. 1901 (no. 781, Perkins). 



(32) Acrittis insolitus, sp. nov. 



Oblongo-ovalis, piceus, nitidus, impunctatus; prosterno conspicue curto ac lato ; 

 mesosterno et parte anteriore metasterni longitudinaliter impressis. Long, i mm. 

 Plate XV. fig. 30, the sterna. 

 This is a smooth impunctate form without conspicuously long legs. Certain
