A somewhat broad, black, not closel}- nor finely punctate species. Head 

 not strongly constricted posteriorly, with two short, stout, cylindrical and 

 ai)ically bifid horns above the excavate scrobes ; face clothed with silvery 

 pubescence ; labruni and (J mandibles flavous ; 9 ^^'ith the palpi and 

 apex of clypeus red. Antennae filiform, nearly as long as the body, black 

 and beneath towards the apex testaceous. Thorax rarely with flavous 

 callosities before the radix ; metathoracic costae wanting, its notum con- 

 vex and very strongly punctate ; 9 petiolar area entire. Abdomen cylin- 

 drical and hardly narrower than the thorax, pubescent, black ; basal 

 segment subsinuate beliind the spiracles and nitidulous ; the second and 

 third subquadrate, usually with a triangular or pyriform fulvous mark ; 

 anal stvles of cJ stout ; terebra hardly as long as the abdomen. Legs 

 slender and fulvous ; J with the front trochanters and anterior coxae 

 flavous, the posterior trochanters and hind coxae black with their apices 

 pale ; 9 ^^'ith coxae black ; hind tibiae apically, tarsi and rarely apices of 

 femora nigrescent ; intermediate tarsi with the joints basally whitish. 

 Wings with the tegulae and stigma fulvous, latter narrow ; nervellus in- 

 tercepted far below its centre. Length, q — ii mm. 



Brischke mentions a variety from Prussia with the palpi, mandibles, 

 clypeus and abdomen red, and the thorax ferrugineous above and below. 

 The second and third segments vary greatly in the extent of the red 

 coloration, which in the (J often occupies all but the basal angles as well 

 as sometimes the apex of the fourth, and in the 9 i^ confined to part of 

 the second and the apex of the third segment. 



This species is instantly distinguished from all the remainder of the 

 genus by the two frontal horns, on account of which Forster erected anew 

 genus, Dihlastomorpha , for its reception. 



It is recorded from Denmark by Thomson. ']"he two co-types of Des- 

 vignes' species — he was not aware of Boie's earlier description — are in 

 the British Museum. Mr. R. Adkin has bred both sexes from larvae of 

 Tortrix palleana, Hb. (Proc. S. Lond. Soc. 1896, p. 82). I possess a male 

 captured at Giff"nock by Mr. A. A. Dalglish in 1899; and have myself 

 found both sexes, upon several occasions, in very marshy spots, from the 

 middle of July to the end of August, in Barnby Broad and Tuddenham 

 Fen, in Suffolk, by sweeping the long and rank herbage. 



2. elongata, Holmgr. 

 Glypta elongata. Holmgr. Sv. Ak. Handl. 1860, n. 10. p. 38; Bridg. Trans. 

 Ent. Soc. 1887, p. 377, j ; Thorns. U. E. xiu. 1339, a' ? . 



A somewhat shining and punctate species, black with fine pubescence. 

 Head not posteriorly constricted, its sides subparallel and vertex broad ; 

 frons unidentate above the scrobes ; palpi and apex of the clypeus testa- 

 ceous. Antennae with the flagellum ferrugineous and darker above ; 

 about half the length of the body in 9 . somewhat more elongate in (^ ; 

 basal flagellar joint longer than second. Thorax black with sometimes a 

 pale callosity before the radix ; metathorax subscabriculous and fully 

 areated in (J, evenly punctate with the costulae and basal costae alone
