before its centre. Abdomen with segments two to four broadly red and 

 nearly glabrous with the epipleurac inflexed ; post-petiole sub-linear, stout, 

 centrally highly arcuate, strongly rugulose, with distinct carinae and nearly 

 central spiracles ; tercbra shorter than the basal segment. Legs slender 

 and red, hind ones a[)ically black ; tarsal claws somewhat stout. Wings 

 griseous, stigma not broad, nervellus post-furcal. Length, 4 mm. 



Bridgman (Trans. Norf. Soc. 1893, p. 615) records this Swedish species 

 from Britain ; he says he has bred it from a spider's nest and captured it 

 at Brundall and the Heigham osier carr, both near Norwich. He seems, 

 however, to rather protest against Professor Thomson's identification of 

 his specimens : " This species I considered //. varitarsus, Grav., with 

 which description it agrees exactly." One must, nevertheless, suppose 

 that Thomson knew his own species.

Head shortly triangular, black, of $ with the palpi and mandibles 

 stramineous with apices of the latter ferrugineous ; frons alutaceous ; 

 vertex narrow and declived ; clypeus deplanate, short and narrow, promi- 

 nent and apically obliquely truncate ; mandibles stout and the cheeks 

 elongate. Antennae inserted low on the face, filiform and shorter than 

 the body ; post-annellus hardly half as long again as the sub-cylindrical 

 and hardly excised scape ; $ with the flagellar joints not discreted and 

 scape stramineous beneath ; $ with the flagellar joints short and conical 

 and the scape ferrugineous beneath. Thorax strongly convex and an- 

 teriorly elevated ; black, with $ propleurae more or less rufescent and 

 the pronotum castaneous ; mesonotum finely punctulate ; metathorax very 

 short, punctulate, with distinct costae and complete areae ; areola strongly 

 transverse, hexagonal and longitudinally rugose ; petiolar area vertical, 

 discreted and reaching far beyond the centre. Abdomen coarctate, oblong-

 laterally and basally ; of $ deplanate and narrower than the thorax, its 

 basal segment deplanate and coarsely punctate with the petiole narrow 

 and not rimose, post-petiole quadrate and a little broader than the petiole, 

 tubercles sub-obsolete and far behind the centre ; of $ as broad as the 

 thorax with the basal segment gradually explanate apically, with the post-

 latter is narrow, basally broadly white and emits the radial nervure from 

 its third i)art ; radix white ; tegulae of ^ stramineous, of $ infuscate ; 

 areolct pentagonal with the outer nervure sub-obsolete ; basal nervure
