A small and slender black species with abdomen narrowly red, legs 

 partly fulvous, and the terebra elongate. Head transverse and not 

 strongly constricted posteriorly ; face inf uscate-pubescent, genal costa 

 sinuately continuous, mandibles weak and apically narrowed, frons not 

 carinate, ^ mouth tiavous. Antennae hardly longer than half body, 

 stout and not apically attenuate. Thorax with propleurae shining and 

 obviously striolate below ; mesosternal epicnemia almost wanting and 

 acetabulae centrally bilobed ; metathorax not deplanate, its central 

 impression apically broad and deep, strongly rugose ; basal areae sub- 

 distinct ; spiracles small. Abdomen compressed and somewhat narrowly 

 red centrally, with the second segment apically concolorous above ; 

 petiole not linear ; terebra somewhat elongately exserted, nearly as long 

 as basal segment. Legs fulvous, their base and nearly always hind femora 

 black ; hind tibiae nigrescent at both extremities ; j with apices of the 

 anterior coxae and of front trochanters pale. Wings with the tegulae 

 flavous and stigma pale ; radial cell broad ; radius emitted from centre of 

 stigma, its apical abscissa not inflexed and a little longer than the basal; 

 lower basal nervure somewhat postfurcal ; areolet oblic]ue, emitting recur- 

 rent nervure beyond its centre. Length, 6-7 mm. 



This species has, doubtless, been mixed in British collections with 

 C. juvenilis, and it has not hitherto been noticed to occur with us ; or 

 possibly mistaken for C . alticola, Grav., which differs from it in having the 

 coxae and trochanters, mandibles and palpi of both sexes black, the third 

 segment nearly entirely red, the tegulae not pale and the 9 antennae 

 shorter and stouter ; the latter has been recorded as British by Marshall 

 under the erroneous genus Linmen'a, but he cannot have known it or he 

 would not have there placed it. 



It has a wide distribution through north and central Europe (Holmgr.), 

 but has not hitherto been noted as British ; it is, however, somewhat 

 common with us, and appears to nearly always be found upon the flowers 

 of umbelliferous plants. A score of specimens, including both sexes, 

 first occurred to me on Heraclcum sphondvl itini flowers in the Minsmere 

 Level marshes near Kessingland in Suffolk on 12th July, 1900; sub- 

 sequently I found it on Dauciis carota at Eye at the end of August, and on 

 umbels growing in the ruined nave of Dunwich church on the Suffolk 

 coast early in July, on Angelica sylvestris in Tuddenham Fen and Ickling- 

 ham marshes towards the end of August in the same county, where Tu("k 

 has taken both sexes at Bungay and Tostock in September, during which 

 month E. A. Butler has sent me the male from Guildford in Surrey.
