eous ; hind tibiae and tarsi entirely infuscate, and their claws not small. 

 Wings hyaline ; stigma testaceous, radius piceous, radix and tegulae stra- 

 mineous ; areolet entire, petiolate and triangular, emitting the recurrent 

 nervure from its apical angle ; radial nervure straight ; ner\^ellus pellucid 

 and intercepting at the basal fourth. Length, 6 mm. 



The colouration of the ^ would appear similar to that of L. errabunda, 

 but the cheeks and frontal orbits are immaculate, the central segments not 

 at all rugose and larger tarsal claws will easily distinguish it. Both sexes 

 are instantly known by their large claws, infuscate hind tibiae and the 9 

 by its transaciculate and not punctate abdomen. 



The female has been found in Sweden and central Europe. It was 

 introduced as British by Bridgman (Trans. Ent. Soc. 1882, p. 163) on the 

 strength of three examples taken by him at Brundall and Earlham, near 

 Norwich ; but no one else appears to have noticed it or, rather, it has 

 probably been overlooked and mixed with L. sulphurifera var. riificoxis, 

 from which the impunctate abdomen, infuscate hind tibiae and shorter 

 terebra easily separate it. ]Mr. Fred. C. Adams takes it commonly in his 

 garden at Lyndhurst in the New Forest, whence Miss Chawner has also 

 kindly sent it to me, from the ist July to the 23rd August, and it is among 

 his specimens that I received the male (described above and now in my 

 collection) on ist August, 1907. Dr. Capron has found females at Shere, 

 in Surrey, and Mr. H.J. Charbonnier at Taunton, in August ; it has oc- 

 curred to me not infrequently in greenhouses at Ryde, in the Isle of Wight, 

 in the middle of August and I have also once taken it at Gosfield, in Essex, 

 on 24th of July, 1902. Nothing appears to be yet known respecting its 

 economy.

J. A slender insect, somewhat shining, alutaceously punctate and 

 black. Head narrowed behind the eyes ; face, mouth, clypeus, cheeks 

 and the internal orbits pale flavous. Antennae subfiliform, though a little 

 attenuate towards their apices, slender, as long as or slightly longer than 

 the body, black and sometimes ferrugineous beneath with the scape always 

 flavescent beneath. Thorax gibbulous ; pronolum entirely or partly, 

 sternum, a line before the radix or only two explanate marks on front of 

 the mesonotum, sometimes a line below the radix, two longitudinal vittae
