as the frontal costa, then similarly expanding to a piece of about the 

 same size as the base with the addition of a triangular plate formed by 

 the inferior and posterior production of the lower outer angle, the api- 

 cal half of the whole incurved, the apical process often bent a little 

 inward, bluntly acuminate, and about reaching the tip of the supra- 

 anal plate; subgenital plate moderate, flaring, of subequal breadth and 

 almost as broad as long, the apical margin a little elevated, broadly 

 rounded, entire.

This and the two following species form a group within the series 

 in which the male cerci are distinctly and considerably decurved at 

 apex. 



Melanophis algidus sp. nov. 



Plate IX., Figure 6. 



Of medium size, moderately stout, rather dark fuscous, dull testa- 

 ceous beneath, with a broad piceous or subpiceous postocular band, 

 generally more distinct in the male than in the female, terminating at 

 the metazona. Head not very prominent, dull testaceous, often and 

 especially in the female with an olivaceous tinge, much obscured with 

 fuscous especially above, the postocular band generally edged narrowly 

 above with testaceous ; vertex gently tumid, distinctly though slightly 

 elevated above the pronotum, the interspace between the eyes about 

 half as broad again (cf ) or twice as broad (?) as the first antennal 

 joint ; fastigium steeply declivent, broadly and scarcely sulcate ; 

 frontal costa percurrent or nearly so, subequal but faintly narrowed 

 above, scarcely narrower than the interspace between the eyes, feebly 

 sulcate below the ocellus, biseriately punctate above; eyes moderately 

 large, a very little prominent in the male, somewhat longer than the 

 intraocular portion of the genas ; antenna; rufous, sometimes a little
