show rudimentary tubercles in some places. Each lateral 

 margin has about twenty-seven or twenty-eight teeth-like 

 small spines in a row on the apical margin, there being seven 

 or eight spines of increasing lengths, although the sutural 

 one is smaller than the next outer one. Underside shining, 

 sparsely covered with whitish hairs. The femora bear minute 

 teeth on the underside. The mid-tibiae curved. The tarsi 

 large. 



Length 6 mm. 



Arabia (type). 



Type in the British Museum. 



There are four more specimens from Turcomania, Kurdestan 

 (Milligen), which strongly resemble the type-specimen, but 

 one of them has the foremost lateral spine doubled, so that 

 instead of three single spines on each side there is a pair on a 

 common base followed by two single ones. This is evidently 

 an instance of abnormality. 



This species differs from inermis, Zoubkoff, and patanine, 

 Weise, in not having prominent costae bearing spines on the 

 elytra and in having three single spines on each side of the 

 prothorax, and from the latter particularly in not possessing 

 a spine on the second joint of the antennae. 



Plddodonta chtrinda, sp. n. 



Body elongate, small, black, subnitid, or opaque. The 

 large dorsal spine on the first joint of the antennae, the great 

 distance between the two pairs of spines on the front border 

 of the prothorax (so that they may be regarded as almost lateral, 

 pointing sideways), the equal, completely separate, and pointed 

 claws, the absence of spines on the elytra, the minute teeth on 

 the lateral margin, and four or five large spines on the apical 

 margin of the elytra — all these characters (which are possessed 

 by this species) separate the genus Phidodonta from all other 

 genera of the Hispinse. This insect, therefore, extends 

 Phidodonta to the African region. 



Head broad, rugose, with a longitudinal deep impression 

 along the middle, and with a row of silvery hairs round each 

 eye. The first joint of the antennae is the largest and bears a 

 dorsal spine, the third joint is longer than the second, which 

 is rounded; fourth, fifth, and sixth rounded and almost equal; 

 these joints are rough and bear a few bristly hairs ; the five 

 apical joints form a thickened club and are covered with 

 brownish pubescence. Prothorax slightly longer than broad, 

 with the surface rugose, scattered over with whitish adpressed
