most authors are content to state is longer than the body ; Gravenhorst 

 gives it as twice or more than twice the length of the abdomen and Tos- 

 quinet says of the var. pcrspicillator, which he considers to be a good 

 species (Ann. Soc. Belg. 1897, p. 308) that it is un tiers plus longue que 

 tout le corps; in my female the body is loi mm. in length, the terebra 

 iz^h mm.

Head with the palpi stramineous or infuscate ; labrum, mandibles 

 except their apices, clypeus, all the orbits and in J two longitudinal 

 facial lines, flavous though less distinct in 9 ■ Antennae as long or 

 nearly as long as the body, subsetaceous and slender ; two basal joints 

 black and in $ flavous or ferrugineous beneath ; remainder infuscate or 

 ferrugineous beneath. Thorax not red marked ; two mesonotal vittae 

 often anteriorly coalesced with the elongate preradical lines, margin of 

 pronotum, propleural lines or dots and a dot before the hind coxae, 

 flavous and less distinct in 9 ; (? also with mesopleurae broadly flavous 

 longitudinally below ; metathorax evenly and scabriculously punctate 

 with petiolar area basally strong ; spiracles small and circular. Post- 

 scutellum, and sides and apex of scutellum, always flavous. Abdomen 

 very finely punctate and a little shining ; basal segment black, either with 

 the apical margin in $ flavous or with the apex broadly red ; the three 

 following red, with the apical margin sometimes flavescent and lateral 

 black marks on the second ; fifth of ^ red, generally more or less exten- 

 sively black on all the margins ; the following black with base of the 

 sixth sometimes rufescent ; second and third segments of 9 a little, of J 

 distinctly, longer than broad ; terebra slightly longer than the body 

 (body 8, terabra 8^, mm.). Legs fulvescent ; coxae and trochanters black, 

 of ^ nearly always flavous beneath and often with the front trochanters 

 entirely fulvous. Wings subhyaline ; stigma and radius infuscate ; radix 

 and tegulae white ; areolet nearly regular, petiolate or subpetiolate. 

 Length, 8 — 9 mm. 



The (5 rarely has the coxae, as in the 9 > immaculate black ; and I 

 possess several 9 9 ^vith the areolet of the wing utterly wanting, though 

 in all other respects quite typical. 



This species may instantly be recognised by the invariably pale 

 postscutellum. It is very like L. insignifcj, with which Bridgman was 

 inclined to synonymize the J, but in 9 th(> aj)ex and sides of the 

 scutellum and the postscutellum, and vittae on the mesonotum are 

 whitish, in J all the coxae are whitish-marked and the mesosternum
