DESCRIPTION OF SPECIES 
NEOTIPHIA, gen. nov. 
This genus is separable from Tiphia by the much longer and nar- 
rower oral opening which extends to, or almost to, the back of the head; 
the glossy post-mandibular triangle so conspicuous in Tiphia is absent 
or linear, and the palpi are very much shorter than in that genus. The 
clypeus is black, and in the genotype male it is pointed below, while in 
the female it is narrowly produced centrally, with the apical outline of 
the produced part rounded. The abdomen resembles that of Paratiphia 
at base, though not so abruptly declivitous on anterior portion of first 
dorsal segment. The hind metatarsi of female have the groove on 
posterior surface long and deep. The venation is similar to that of 
Tiphia. 
Genotype, Neotiphia acuta, sp. n. 
NEOTIPHIA ACUTA, Sp. n. 
Male.—Black, glossy ; palpi yellowish; tarsi brown; wings yellowish 
brown except at apices; veins and stigma black-brown; hairs white. 
Face doubly punctate above antennae, on other portions with large 
and rather widely spaced punctures; clypeus subtriangular, terminating 
in an acute point below, surface with dense, minute punctures, and 
larger punctures bélow; antennae submoniliform below; mandibles 
simple; palpi much shorter than in Tiphia, apical joint of maxillary 
palpus not over four times as long as its greatest diameter; oral opening 
narrow, its length more than 1.5 its posterior width, nearly parallel- 
sided, extending nearly to posterior margin of head; post-mandibular 
triangle absent; cheeks with sparse large punctures. Pronotum with 
large deep punctures; mesopleura with large, deep subcontiguous punc- 
tures. Metathoracic enclosure narrowed posteriorly, posterior face of 
metathorax slightly rugose below, doubly punctate on greater portion 
of surface. Basal dorsal abdominal segment with an incised line at 
middle, which is distinctly angulate centrally; punctures on disc of seg- 
ment large, no impressed apical line present; remaining segments, ex- 
cept apical, with large shallow punctures which are closer near anterior 
and posterior margins, forming usually a single transverse line; segments 
1-5 each with a broad impunctate apical margin; sixth segment with 
large, deep, contiguous punctures; ventral segments similar to those of 
dorsum, the basal segment flattened as usual, and the sixth with much 
smaller punctures and a very conspicuous broad shallow channel in
