 393. i ? • 



Head tumidous, not narrowed posteriorly, black ; vertex broad ; frons 

 hardly shining ; apex of clypeus sub-sinuate centrally ; mouth partly rufes- 

 cent. Antennae l)lack, flagellum ferrugineous beneath in (J, basally in $, 

 which latter has a central white flagellar band. Thorax black ; pronotum 

 of $ dull red ; notauli hardly indicated ; areola jjentagonal, a little longer 

 than broad, basally rounded and a[)ically truncate ; petiolar area hardly 

 impressed, transversely rugulose. Scutellum black. Abdomen narrow, 

 black ; $ with central incisures usually rufescent, ? with apex of first 

 segment, whole of two to four red, and apices of the following pale ; 

 post-petiole partly aciculate ; base of second segment normally impressed. 

 Legs red ; hind ones with base of coxae, apex of femora, base and apex of 

 tibiae, and the tarsi, infuscate ; hind femora linearly impressed beneath ; 

 coxae mutic. Stigma and tegulae piceous ; radix white. Length, 6-8 mm. 



The variety vitermedius differs only in colour from the type form ; the 

 thorax is entirely black, the anterior legs have the coxae, trochanters and 

 tarsi infuscate, and the hind pair are darker ; the $ antennae are not, or 

 very indistinctly, white-banded ; the $ pronotum is black, and its central 

 segments are entirely red. 



Bridgman's record {Joe. cil.) of " four males from Gunton by Cromer " is 

 possibly a slip for Runton, though it is perpetuated at Tr. Norf. Nat. Soc. 

 V. p. 610; he took them all on August ist, 1887, one being referable to 

 the var. intermedins ; Rev. T. A. Marshall is said to have also captured 

 the species. On the Continent it occurs in Belgium and Sweden. 



4. guttulatus, Grav. 



IchneiDiion guttulatus, Gr. I. E. i. 580, excll. varr. ; Ste. 111. INI. vii. 201, 9- Dia- 

 dronius guttulatus. Berth. Ann. Soc. Yx. 1896, p. 361 ; cf. Wesm. Mem. couron. Ac. 

 Belg. 1859, p. 70, ? . 



Head finely and closely punctate, black ; apex of clypeus sub-sinuate 

 centrally ; mandibles and palpi ferrugineous ; facial orbits in part white. 

 Antennae slender, filiform, black ; apically, and towards the base beneath, 

 ferrugineous ; centrally white-banded. Thorax black ; pronotum and cal- 

 losities before and beneath the radix white. Abdomen black, with the 

 post-petiole, whole of segments two to four, part of five, and incisures of 

 remainder, red. Legs slender, red ; base of coxae and the hind tarsi 

 infuscate ; hind femora linearly impressed beneath. Stigma fuscous ; 

 radix and tegulae flavescent. Length, 7 mm. 



The propriety of including this species in the present genus must be 

 regarded with some doubt, since nothing appears to be known of it beyond 

 the type specimen examined by Wesmael, who, comparing it with D. vari- 

 color, says, " la limite entre le chaperon et la face plus nettement indiquee 

 par une lineole transversale enfoncee." 



Found at Coombe Wood, in June (Stephens) ; Gravenhorst records it 

 from Germany, in June, but I know of no authentic British example, and 

 its right to inclusion in our fauna is doubtful. 



5. candidatus, Grav. 



Ichneumon candidatus, Gr. I. E. i. 193 ; Ste. III. M. vii. 145, i . Diadromus can-
