Glypta evanescens, Ratz. Ichn. d. Forst. ii. 103; Thorns. O.E. xiii. 1333, i ? ; 

 cf. Bridg. Trans. Ent. Soc. 1889, p. 436 ef E.M.M. 1890, p. 208. 



Head somewhat strongly constricted behind the eyes, with long and 

 sparse grey pilosity ; epistoma not at all prominent ; clypeus and whole 

 mouth of ^ stramineous, of 9 rufescent, the former almost longer than 

 apically broad, with large and shallow punctures ; frons mutic, transversely 

 impressed above the scrobes, deeply and evenly punctate with the inter- 

 stices smooth ; palpi pale. Antennae about as long as the body, filiform 

 and slender ; 9 flagellum testaceous apically below, ^ with the scape 

 stramineous and the flagellum testaceous throughout beneath. Thorax 

 black with a flavous callosity before the radix; mesonotum shining, finely 

 and not very closely punctate, with distinct notauli ; metanotum strongly 

 elongate, pilose and exareated ; petiolar area extremely short with dis- 

 tinct basal carina. Scutellum laterally and apically, with the frenum 

 narrowly, flavous. Abdomen linear-cylindrical and narrower than the 

 thorax, black and nearly smooth with grey pilosity ; basal segment twice 

 longer than apically broad, hardly sinuate behind the spiracles, with the 

 obsolete discal carinae quite ( 9 ) or nearly (J') reaching the apex; cen- 

 tral segments very distinctly longer than broad, with the oblique impres- 

 sions basally confluent ; terebra as long as the six basal segments. Legs 

 fulvous ; the anterior flavous with the coxae and all the trochanters 

 stramineous ; hind pair with tarsi, apices of tibiae and 9 calcaria infus- 

 cate. Wings hyaline ; stigma dull testaceous, radix and tegulae stramin- 

 eous ; fenestrae discreted ; first recurrent antefurcal and intercepted, 

 especially in 9 > far below the centre. Length, 9 — 10 mm. 



Bridgman truly says that this species may be known from both G.JIaro- 

 lineata and G. cicatrkosa by the central segments being longer than broad ; 

 and adds that they are at least half as long again as broad, lending the 

 insect the elongate facies of Ephialtes. 



I possess four specimens, including one female, taken by Dr. Capron 

 about Shere, in Surrey, as mentioned (/.c.) by Bridgman, when introducing 

 the species as British. Mr. Stanley Edwards took another female at 

 Lynton in i8go. It was originally bred by Ratzeburg from Halias qiicr- 

 cana in Prussia, as indicated by Kirchner.

Somewhat curved, dull and clotlied with grey pubescence. Head con- 

 stricted behind the eyes, black with the face obscurely red and furnished 

 with short white hairs ; mandibles castaneous, cheeks normal ; clypeus 

 red and apically densely pubescent ; frons mutic, evenly punctate and 

 somewhat shining. Antennae subfiliform, ferrugineous above and fulvous
