46 Mr. M, Jacoby's Descriptions of New Genera and 



any other, also distinguished by the elytral sculpture. I 

 possess a single specimen without detailed locality. 



Megalognatha shepparcli, sp. n. 



Fulvous, antennaj flavous, the last two joints black, thorax with 

 three depressions, elytra minutely and not very closely punctured, 

 black, a subquadrate patch at the middle flavous. 



Var. Elytra entirely black or fulvous. Length 4 millim. 



Head impunctate, fulvous, frontal elevations very highly raised, 

 trigonate, bounded behind by a deep transverse groove, anterior 

 margin of the clypeus straight, labrum and palpi flavous, eyes 

 prominent, antennae slender, the third and following joints elongately 

 subquadrately widened, the last two joints black, terminal one elongate 

 and slender, thorax about one half broader than long, slightly con- 

 stricted at the base, the disc with a small triangular depression at 

 the middle near the anterior margin and a large deep fovea at each 

 side, fulvous, impunctate, Avith the exception of a few punctures 

 which surround tlie anterior fovea, scutellum fulvous ; elytra with 

 very fine but rather remotely-placed punctures, the basal portion 

 raised, depressed at the suture, black, this colour interrupted by an 

 elongate subquadrate, flavous patch at the middle, extending across 

 the suture, under-side and the femora fulvous, the tibiae and tarsi 

 flavous, last joint of the latter, fuscous, tibiaj unarmed, the meta- 

 tarsus of the posterior legs as long as the following joints together, 

 claws appendiculate, anterior cotyloid cavities open. 



Eah. Beira (P. A. Shcpimrd). 



Although this species is less typical of the genus than 

 most of its congeners, since the thorax is of rather more 

 transverse shape, and the sutural margins are not thickened, 

 yet the thoracic depressions and the open coxal cavities 

 and unarmed tibioe agree better with Megaloynatha than 

 with any other genus of Galcrucinm. The specimen, 

 which seems to be of the male sex on account of the long 

 antennae and their widened joints, which are very similar 

 to those of several species of the genus Platyxantha, has 

 a deep cavity in the first abdominal segments, but whether 

 this is accidental or normal I am unable to say. The 

 elytral coloration seems very variable. 



Megalognatha inconspicua, sp. n. 



Testaceous, the antennre, tibijB and tarsi black, Jiead, thorax and 

 femora fulvous, the thorax finely and sparingly punctured with an
