NO. 2031. NEW VARIETIES OF ICHNEUMON-FLIES— VIERECK. 373 



the liind tibiae which are brownish, in the wings, which are distinctly 

 tinged with brown and have a black stigma and dark-brown veins, in 

 the black propodeum, and in the abdomen, which is black except for 

 the lateral margin and the apical margin laterally on the second seg- 

 ment as well as some of the margins of the ventral segments, all of 

 which are more or less stramineous. A series of paratopotypes of 

 both sexes indicate that this is a constant species. 

 Named in honor of Dr. W. Roepke. 



DIGONOCRYPTUS, new genus. 



Type. — Digonocryptus bidens, new species. 



Related to Hoplocryptus Thomson, from which it differs in the 

 clypeus having a transverse elevation that is emarginate medially, in 

 the anterior edge of the clypeus being bidenticulate, in the mterstitial 

 nervulus, in the parallel sided areola, in wantmg an apical transverse 

 carina on the propodeum except for a bare indication in the form of 

 an elevation of the tegument on each side and by the virtually non- 

 carinate first segment. 



DIGONOCRYPTUS BIDENS, new species. 



Type-locality. — Villa Morra, Asuncion, Paraguay, April 10, 1905, 

 J. D. Anisits. 



Type. — Konigliche Zoologische Museum, Berlm. 



Female. — Length, 11 mm.; black and shining; head, thorax, and 

 then- appendages colored in much the same way as in the genotype 

 of Monogonocryptus Viereck, except that the basal half of the man- 

 dibles, which is mostly yellowish, the mesopleurae, which are yellowish 

 except along the edges and along the sternauli, m the mesosternum 

 which is brownish with a yellowish mark posteriorly, in the pro- 

 pleura?, which are yellow laterally and posteriorly, in the fore and 

 mid femora, which are yellow above and strammeous at the base, in 

 the hind legs, the coxae, trochanters, and base of femora of which are 

 brownish except for the yellowish white superior face of the coxae, 

 their femora mostly black, their tibiae and tarsi yellow except the 

 claws and empodii, which are brown and in the metapleurae and sides 

 of the metanotum, which are mostly yellow; propodeum with its 

 confluent basal area almost polished with a yellow area on each side 

 near the spiracles and at the base in the middle, rest of the propo- 

 deum striate with a yellow border on each side and a yellow band 

 down the middle, the apical transverse carina angularly produced on 

 each side ; dorsal abdominal segments with a yellow border laterally 

 and apically excepting the apical segment, which is bordered with 

 yellow only laterally, venter yellowish excepting the second and 

 third segments, which are more or less brownish, sheaths of the 

 ovipositor apparently as long as the first and second, abdominal seg- 

 ments combiued.
