with the scape, pedicellus and two Ixisal flagellar joints red, the latter 

 sub-equal and more than thrice longer tiian broad ; of 6 piceous, densely 

 pul)escent with the first flagellar joint l)asally flavidous. Thorax black 

 with yellowish pubescence ; notauli very distinct and in 6 basally coalesced ; 

 nietathorax dull and densely pubescent with the costae strong ; areola 

 subparallel-sided, of 9 transverse and a[)ically emarginate, of i elongate 

 and apically truncate ; petiolar area discreted ; apophyses wanting. Abdo- 

 men of ? glabrous, shining and sparsely pubescent and ovate, of ^ sub- 

 cylindrical with the basal segments distinctly punctate ; segments two to 

 four or five and the apex of the first red or castaneous, with their apical 

 margins paler ; basal segment bicarinate throughout, hardly explanate, 

 with distinct tubercles, of $ sub-linear and laterally margined, with the 

 tubercles obsolete ; second segment elongate, third of ? sub-transverse, 

 of c^ quadrate ; terebra black with the spicula red, half the length of the 

 abdomen. Legs slender, somewhat elongate, with the posterior tarsi 

 infuscate, remainder red. Wings slightly clouded, stigma black, radix and 

 tegulae pale ; nervellus antefurcal ; fenestrae narrowly discreted. Length, 

 5~6 mm. 



Gravenhorst says If. argentatiis is like H. feni/icornis, but with the 

 antennae stouter and nietathorax mutic ; Bridgman adds that the 9 of 

 H. gyrini is very similar in shape to H. formosus, but the basal segment is 

 shorter and stouter, and that the $ resembles Orthopelma biteolator, 

 though it is yet more slender ; this $ is, however, a much slighter insect, 

 with longer legs, wings and antennae. 



I am certainly of opinion, from a comparison of the descriptions and a 

 study of Parfiit's types, that Thomson's supposition regarding the synonymy 

 of these species is correct, at all events in so far as Gravenhorst's inade- 

 quate notes allow one to judge ; and I anticipate that its more natural 

 position is to be found in the genus Panargyrops. 



Hope sent a female H. argentatus to Gravenhorst, taken about Netley 

 in Shropshire, which is neither in the latter's collection nor in that of Hope 

 at Oxford (cf. Entom. 1883, p. 102) ; Bridgman records it from Brundall 

 near Norwich, in May. Mr. Parfitt first bred the males of his // gyrini 

 in the autumn of 1880 ; early in the following July he bred females from 

 spring pupa-cases, and Bignell also raised it, from pupae of Gyrini/s 7iatator 

 found by the Rev. J. Hellins upon rushes on the banks of the Exeter 

 Canal, of which the latter has allowed me to examine both sexes ; it is 

 later recorded as bred from the same host, together with Pezomaclius 

 (?)vidines, Forst. One is led to wonder whether the latter could have 

 been a dimorphic female of the same species.

.Smooth, shining and black. Head transverse, slightly narrowed behind 

 the eyes and anteriorly triangular ; clypeus apically sub-truncate, face 

 finely punctate, frons deeply foveate. Antennae three-quarters length of 

 body, sub-filiform and slightly incrassate apically, with the three basal 

 flagellar joints sub-equal in length and nearly thrice longer than broad. 

 Mesonotum very finely punctate with distinct notauli ; metathoracic areae
