Head not constricted posteriorly; clypeal foveae not setiferous; face 
centrally elevated and strongly punctate; palpi white, mandibles centrally 
fulvidous, face and clypeus black. Antennae a little longer than half 
body, subsetaceous; scape black. Thorax with meso-notum and -pleurae 
punctate and nitidulous; metanotum completely areated, with strong 
costulae. Abdomen with two basal segments rugose and shining, the 
former’s carinae extending to centre; second and third segments with red 
fascia, remainder black, shining and narrowly flavous-margined. Legs 
with coxae and trochanters black, latter apically paler; anterior tibiae 
and tarsi fulvous; hind femora stout, fulvous and apically black, their 
tibiae basally fulvous with remainder, like their tarsi, black. Areolet 
large, oblique, irregular, subpetiolate and hardly complete; stigma 
piceous; nervellus intercepted far below its centre. Length, 6 mm. 
This species stood under Zryphon in our last (1872) catalogue, but 
Giraud transposed it to the present genus (cf. Bridgman, Trans. Ent. Soc. 
1882, p. 158) and its position is confirmed by Pfankuch, from whose des- 
cription of the type the above is mainly drawn. 
The original male was captured in Hercynia in June; and elsewhere it 
is only recorded from France, where it has been bred from JZesoneura 
opaca (Dineura verna) by Giraud. Our sole claim to this species as indi- 
genous rests upon Stephens’ record “Scarce; found in June near Lon- 
don,” published in 1835; no one has mentioned it here since that time 
and it must be regarded as very doubtfully British. I possess a single ¢, 
which I here place with grave misgiving, since the antennae are much 
longer than in any other of the species; I swept it from hazel bushes on 
16th June, 1902, in the Bentley Woods near Ipswich. 
GRYPOCENTRUS, Ruthe. 
Ruthe, Stett. Ent. Zeit. 1855, p. 51. 
Head subbuccate, generally somewhat dilated behind the eyes; face a 
little prominent; clypeus deeply discreted, strongly elevated and apically 
ciliate ; mouth not entirely closed, labrum not exserted ; mandibular 
teeth nearly always of unequal length, the lower the shorter. Antennae 
shorter than body, of nineteen to twenty-one joints with the pedicellus 
large and basal flagellar joint hardly double its length. Metathorax short 
with the discal areae subdistinct though incomplete. Abdomen subsessile 
with the basal segment gradually dilated apically, not discally carinate, 
very rarely subpetiolate and slightly curved; terebra distinctly reflexed 
and not exserted. Legs normal with hind tibiae stout and basally con- 
stricted, calcaria short, tarsi pectinate. Wings somewhat ample ; areolet 
pentagonal, subtriangular or wanting; stigma large; radial cell short and 
subtrapeziform. 
A genus of very small species (almost—with those of the following— 
the only very small species in the Tryphonides), with large head, short
