the median part, flattened inwardly and ending in a short mucro 

 l)earing the apical spur ; hind claws single, simple ; anterior tibiae 

 quadri-dentate, the basal tooth is shorter than the other three, and 

 there are two or three serrate teeth above it. 



Female : Like the male, but the scales on the pygidial part and 

 abdomen are whiter. 



This species is a little less elongated than the other species of this 

 section, and is a good transition form. 



Length 4 mm. ; width 2^ mm.

Heterochelus (Ischnochelus) timidus, Bunu., 

 Handb. d. EntomoL, iv., 1, 1844, p. 130. 



Male : Black, with the elytra light testaceous, but somewhat 

 infuscate in the anterior part, legs rufescent ; head very briefly 

 pubescent, and very rugose, clj'peus straight, shai'ply angular on each 

 side but not denticulate in the centre ; prothorax very closely 

 scabroso-punctate almost all over, very briefly pubescent, but having 

 along the base and also the outer margin a narrow band of slightly 

 flavescent, appressed, sub-squamose hairs, and a few similar ones in 

 the posterior part of the deep, median sulcus ; scutellum densely 

 scaly ; elytra hardly distinctly costulate and having along the suture 

 a broad band of somewhat closely set, ovate, flavescent scales which is 

 continued round the apical part, and ascends along the outer margins 

 to the humeral part, the space between this sutural and outer 

 marginal band is filled with somewhat remote but similar scales 

 which do not, however, form bands ; the apical part of the pi'opygi- 

 dium and thepygidium are densely covered witli thick, sub-lanuginose 

 yellow scales, and the abdomen with elongate white ones resembling 

 appressed hairs but thicker ; hind tibiae as in the preceding species, 

 apical spur long. 



Female : Like the male, but the elytra are a little less infuscate 

 behind, and the scales are replaced by squamifmui hairs. 



Length 4-4i nmi. ; width 2-2^ mm.

Heterochelus (Ischnochelus) parentalis, n. spec. 

 Female : This species is very closely allied to II. timidus, and it 

 might prove to be a large varietal form of the same. The male is 

 unknown to me, but in the female the straight clypeus is l)i-denticu- 

 late in the centre at apex ; the sculpture and vestiture of the head 

 and prothorax are the same, the elytra are reddei" but also slightly
