65. validicornis, Thorns. 

 Ilcinitclcs validicornis. Thorns. O. E. x. 995 ; Schm. Term. Fiiz. 1897, p. 550, 9 . 



Black. Frons shining and sub -glabrous, mandibles and palpi red. 

 Antennae black, as long as the body ; of ? distinctly incrassate apically, 

 with the basal half red ; of c? filiform throughout, and not incrassate ; 

 pedicellus internally mutic. Mesonotum shining and nearly smooth ; 

 metathorax nitidulous and sub-glabrous, with the costae strong and entire ; 

 areola sub-circular, apophyses small. Abdomen glabrous and nitidulous, 

 red with segments three to six, sides of the second and sometimes in ? , 

 always in (?, first, black; anus pale; post-petiole aciculate and bicarinate, 

 bordered throughout ; epipleurae of the second and third segments acutely 

 inflexed ; terebra nearly as long as the first segment. Legs red, hind 

 coxae of $ basally, and their tarsi, piceous. Wings with the lower angle 

 of the discoidal cell not obtuse ; nervellus sub-opposite and intercepted 

 below centre. Length, 4 mm. 



Thomson, who leaves one uncertain as to the alar development, though 

 Schmiedeknecht places it among the macropterous species, says it differs 

 from heinipterifs, Esenbecki and pedestris in the petiolar area reaching a 

 little beyond the centre of the metanotum, the second segment with fine 

 and scattered punctures and the front tibiae not inflated. 



A specimen, or specimens of this Swedish species, taken at Eaton in 

 Norfolk, in September, was named by Professor Thomson (recorded in 

 Trans. Ent. Soc. 1886, p. 104), which Bridgman had considered to be 

 H. vielanopygus^ Grav., nor could he afterwards detect wherein it differed 

 from Gravenhorst's description. Schmiedeknecht relies upon the ab- 

 dominal coloration. The male has not before been described ; both 

 sexes are well represented in Capron's collection, probably from Shere 

 in Surrey. 



66. politus, Bridg. 



Hemiteks politus, Bridg. Trans. Ent. Soc. 1883, p. 146; Schm. Term. Fiiz. 1897, 

 P- 551. ?• 



A shining species, covered with very scattered, erect, stiff hairs. Head 

 transverse, laterally rounded and posteriorly declived ; face transverse with 

 inner orbits slightly emarginate next antennae; epistoma sub-prominent; 

 clypeus distinctly discreted and apically broadly rounded. Antennae 

 filiform and shorter than body ; scape not longer than broad ; flagellum 

 basally, and to the centre beneath, red. Thorax longer than high and 

 narrower than abdomen ; mesonotum slightly wrinkled with faint notauli ; 

 upper metathoracic areae distinct ; areola longer than broad, hexagonal ; 

 apophyses prominent, petiolar area sub -discreted. Abdomen broadest 

 centrally, black, with second and base of third segment red ; basal seg- 

 ment gradually explanate throughout, sub-canaliculate and glabrous, with 

 prominent spiracles, and the following segments transverse and glabrous; 

 terebra straight, two-thirds length of abdomen. Legs slender, red ; base 

 of coxae sometimes infuscate, apices of hind femora and base and apex of 

 their tibiae nigrescent. Wings slightly infumate ; radix and base of the 

 piceous stigma white ; areolet pentagonal with outer nervure wanting ; 

 lower external angle of discoidal cell sub-acute ; nervellus insterstitial, 

 slightly post-furcal. Length, 3|~4 mm.
