180 THE ENTOMOLOGIST. 



Striolatvs, Thorns. 



I must refer to this species an insect taken on the Gog Magog 

 Hills, Cambridge, on July 8th, 1917. It agrees with Thomson's 

 description in having the 8rd abdominal segment *' acciculato- 

 puuctato," but has the terebra two-thirds as long as the abdomen. 

 The first three abdominal segments are coarsely and irregularly 

 striolate with i)unctulate interstices (in which it differs greatly 

 from exsertor, Nees) ; metathorax rugulose ; orbits and lateral 

 lobes of mesothorax rufescent ; legs testaceous, hind coxfe dark, 

 all the tarsi, hind femora and tibise apically piceous, middle 

 femora and tibife also darker at the tips ; stigma fuscous with 

 rather more than the inner third flavous ; antennae 34-jointed. 



The only other British specimen so far recorded was taken in 

 Suffolk in 1899 by Morley, who informs me that it has similar 

 dark markiugs on the legs ; this is a character not mentioned by 

 Thomson. 



Gracillipes, Thoms.* 



First recorded as British by Morley, who mentions two 

 specimens — one taken at Greenings in 1872 and the other at 

 Appledore in 1900. The species seems to be rare and I have 

 only once met with it, namely on May 16th, 1910, when a 

 female was taken by sweeping hawthorn bushes at; Becton Bunny 

 on the Hampshire coast. In this example the third abdominal 

 segment is pale testaceous at the apex while the following 

 segments are entirely of that colour ; the antennae are dark 

 above with the exception of the extreme base of the first joint of 

 the flagellum ; 33-jointed. According to Thomson it is easily 

 distinguisbed from cunctator, Hal., by the greater length of the 

 second abscissa of the radius when compared with the first. 



Excuhitor, Hal.f 



On June 3rd, 1917, I captured two females on the Gog 

 Magog Hills, Cambridge, and on June 6th, 1918, a single male in 

 a lane at Hunstanton, Norfolk. These insects would agree 

 exactly with Haliday's description but that the third and follow- 

 ing segments are not apically pale in the male and one of the 

 females ; this slight colour variation is, however, of little moment. 

 Antennae 33-34-jointed. The male has the mesothorax centrally 

 rufescent. Hind femora entirely pale testaceous. A larger 

 insect than tennicornis, Thoms., and the median spiracles on the 

 first abdominal segment are much smaller. 



Tenuicornis, Thoms. 

 An addition to our British list ; a single male was swept from 

 grass on the Gog Magog Hills on July 8th, 1917. Distinguished
