Form flat, rather short and broad ; prosternal 

 process short, a little curved upwards, broad at 

 the apex, truncate and not ciliate ; head trun- 

 cate immediately behind the eyes, which reach 

 to the hind angles; tarsi rather largely de- 

 veloped, lobes of the third joint comparatively 

 elongate and slender. 



Porm rather broad and parallel, but only mode- 

 rately elongate and depressed ; prosternal pro- 

 cess scarcely curved upwards at the apex, which 

 is very broad and ciliate ; hind portion of head 

 oblique behind the eyes; tarsi rather broad, 

 lobes of the third joint rather long. 



Form narrow and very elongate, parallel, not ex- 

 cessively depressed ; prosternal process not 

 curved upwards at the apex, which is broad and 

 ciliate ; hind margin of head slightly oblique 

 behind the eyes ; tarsi not broad, lobes of the 

 third joint distinct but not elongate. N.B. — 

 These characters, with the exception of the 

 form, are not very different from those assigned 

 to the Brachypeplus rohustus, and the two 

 may, perhaps, be correctly associated in a first 

 synthesis. 



Form excessively depressed (scarcely thicker than 

 a sheet of writing paper), parallel and elongate; 

 prosternal process not curved upwards at the 

 apex, which is moderately broad and ciliate ; 

 hind margin of head truncate behind the eyes ; 

 tarsi quite narrow, lobes of the third joint quite 

 undeveloped. 



Form rather broad and short, much acuminate 

 at the hind extremity, moderately depressed ; 

 prosternal process short, its extremity slightly 

 directed upwards, not ciliate ; head not quite 

 truncate behind the eyes, which do not extend 

 to the hind angles ; tarsi rather broad, but 

 short, with the lobes of the third joint little or 

 moderately developed. 



N.B. — This group approaches to the Brachy- 

 peplus discedcns group (by means of Bracliy- 

 peplus aper'), from which its distinctive charac- 

 ters are the less of development of the eyes and 

 tarsi ; the Bracliypeplus brevis is the species 

 in which the diminution of these parts reaches 

 its greatest extent. The group appears to 

 approximate to the subgenus Selis of Murray, 

 which is composed of three species from Batchian 

 and Mysol.
