punctured, the sides of the middle lobe and the furrows strongly 

 closely striated. Scutellum weakly punctured, more strongly on the 

 top of the apical slope ; the apex of the latter is smooth. Sides of 

 post-scutellum obliquely striated. Basal region of metanotum 

 closely reticulated ; the area distinct, narrowed towards the apex, 

 but with the keels not meeting there ; the space between the two 

 keels is stoutly, closely obliquely striated ; the apical slope is 

 stoutly striated; the striae on the middle transverse, on the sides 

 more oblique ; the two transverse keels are distinct, stout ; the 

 basal is slightly dilated at the sides, the apical bears a broad, 

 bluntly pointed tooth. Metanotal spiracles about four times longer 

 than wide. Tarsi closely spinose. The head, thorax, and coxae 

 are covered with a white pile. 



Apart from the absence of red marks on the head, this species 

 may be known by the stout transverse keels on the metanotum and 

 by the distinct basal area. 



Cryptus rufoplagiatus, sp. nov. 



Black, a narrow line, broadest below, on the outer orbits, the 

 mesonotum, except the sutures, scutellum, a broad line on the centre 

 of the pronotum, a narrower, longer one on the lower edge of the 

 propleurae, tubercles, a large, quadrangular mark on the hinder 

 two-thirds of the mesopleurae above, a triangular mark below the 

 hind wings, blood-red ; a narrow line on the inner orbits, an 

 in-egular mark, broader than long, in the centre of the face, a 

 large mark on the upper half of the clypeus and the basal half 

 of the mandibles, pale yellow. Four front legs yellow tinged 

 with red ; their coxae and trochanters black, their femora broadly 

 black above ; the hind legs obscure rufous ; the coxae above, 

 trochanters, tibige behind, the basal joint of the tarsi, the second 

 except at the base and the apical joint, black, the rest white. 

 Wings hyaline, iridescent, tinged with violaceous, the stigma and 

 nervures black. ^ .

Face and clypeus closely punctured. Upper half of front in the 

 middle closely, somewhat strongly transversely striated. Meso- 

 notum weakly punctured, the scutellum smooth. Metanotum 

 opaque, finely rugose, the apical slope finely, irregularly striated ; 

 the basal keel is roundly curved backwards in the middle ; it, and 

 the apical, are not very distinct ; the teeth are indistinct. The red
