the basal depression is large, deep, and bears stout keels. The trans- 

 verse cubital nervures slightly converge above. The petiole com- 

 mences to become gradually wider from shortly behind the middle. 

 In Ashmead's arrangement (Bull. U. S. Mus., xxiii, p. 41), this 

 genus would come near Qryptus and Itamoplex, with neither of 

 which can it be well confounded. 



Cosniiocryptus Tiolaceipeuiiis sp. nov. 



Black ; the 5th to 8th joints of the auteniifE white above ; the'abdomen and 

 the hinder coxse, trochanters and femora ferruginous; the wings uniformly 

 purple-violaceous, stigma and nervures black, 9 . Length 13; terebra 3 mm. 



Antennffi black, slender, slightly more thickened before the apex ; the scape 

 shining. The front irregularly transversely striated above; the depressed lower 

 part is more shining and is rather strongly, more widely obliquely striated. Face 

 aliitaceous ; theclypeusis more shining in the middle and aj)ex where it is sparsely, 

 minutely punctured. Labrum smooth, shining and whitish. Mesonotum closely 

 punctured, more strongly and less closely at the apex than at the base, the parap- 

 sidal furrows do not reach to the apex ; between them, at their apex, are some 

 stout, irregular keels. In the centre of the scutellar depression are five stout 

 longitudinal keels. The base of the metanotuni is longitudinally striated, finely 

 and closely at the base, more widely and strongly towards the keel ; the rest is 

 coarsely reticulated ; the apical slope more closely and less strongly than the rest ; 

 in the middle, at the base, is an area which is wider than long, transverse at the 

 apex, rounded at the base. Pleurae stoutly, irregularly longitudinaly striated, 

 except the meso- at the apex abo-ve and at the base below ; the furrow is wide, 

 deep and stoutly striated. The wings have brilliant purple and violaceous reflec- 

 tions ; the 2nd transverse cubital and the recurrent nervures are largely bullated. 

 Abdomen smooth and shining.

Callicryptus oriiatipeiini!<» sp. nov. 



Dark ferruginous, the basal 13-14 joints of the anteunaj pale yellow, the apical 

 black; the hinder tibiae blackish, the tarsi pale; wings yellowish-hyaline, a 

 fuscous cloud behind the transverse basal nervure, a similar cloud at the stigma, 

 dilated outwardly in the middle and a wider one on the apex, fuscous; the last 

 two are united by a broad band on the lower side; the nervures and stigma 

 yellowish-testaceous; the hinder wings fuscous at the apex, 9 • Length 13 mm. ; 

 terebra 6 mm. 



AntenniB stout, shorter than the body; the scape dark ferruginous below. 

 Head shagreened ; the face with a microsco])ic pile ; the clypeus sparsely 

 covered with long black hairs. Mandibular teeth black ; the palpi dark rufous, 

 thickly covered with pale hair. Pro- and mesothorax shagreened, almost bare. 

 The median segment at the base in the middle distinctly, but not very closely, 

 punctured ; the sides more finely and closely punctured ; the rest closely, irregu- 

 larly rugosely punctured. The basal cloud bisects the lower part of the trans- 

 verse basal nervure and is slightly wider on the lower side; the middle cloud 

 has the upper half oblique and extends to and occupies the areolet ; its lower part 

 is roundly curved on the innerside. and is bounded outwardly by the recurrent 

 nervure. The basal 2 segments of the abdomen are darker colored than the apical.
