This species is entirely cosmopolitan, and occurs in all ports almost 

 throughout the world. In temperate climates it appears only to be able to 

 live under conditions of artificial heat, and so is probably of tropical origin. 

 It seems to be extremely numerous everywhere. The synonymy has been 

 established by de Bormans. In his later work (1900) de Bormans separates 

 A. arachidis and A. gravidula. 



APTERYGIDA Bl PARTITA (Kirb.). 

 Slender, elongate. Head shining, red ; eyes black ; antennas darkish- 

 testaceous, with 12 segments. Pronotum slightly narrower than the head, 

 and of the same colour, eometimes varied with testaceous. Elytra long, 

 gokleu-yellow, with a darker band on the suture and outer border. Wings 

 projecting well beyond the elytra, and of the same colour. Feet pale, 

 testaceous. Abdomen of a rich dark-red, shining, all the segments, and to a 

 less extent, the forceps also, finely and densely puQctulated ; the glandular 

 folds of the second and third segments are very distinct and black. The anal 

 segment is narrow, impressed in the middle, the angles sharp. The forceps 

 in the $ are dimorphic ; the branches are slender, wide apart and straight 

 with a flattened triangular dilatation in the form of a tooth at the base on the 

 inner margin ; after that they are simple and unarmed ; in one form they are 

 short, and straight, very slightly incurved at the apex, where they scarcely 

 meet ; in the other form they are much longer, and the apices meet, and 

 are more or less strongly curved upwards. In the $ the branches are 

 stouter, contiguou?, straight, conical, and unarmed,
