brownish ; cubital almost effaced, only a faint vestige appearin}^ 

 beneath the 1st cubital areolet. Legs piceous, the hind pair nearly 

 black ; trochanters and knees testaceous. Abdomen us long as the 

 head and thorax ; 1st segment linear, at least three times as long as 

 broad ; tubercles minute. Length, | ; exp. If lines. 



Two males were reared by Bignell out of a species of 

 aphis found on Eupliorlia paralias, the sea-spurge. This 

 aphis is perhaps Aphis euphorhiie of Koch and Kalten- 

 bach, but I find no mention of it in Buckton's monograph. 

 The $ Aphidius corresponds very closely with the $ of 

 sp, 19, pseudoplafani, but there can be no proof of their 

 relationship without breeding, and considering the differ- 

 ence of their origin, T have not united them.

$ Blackish brown, paler on the abdomen ; the 1st segment 

 yellow. Oral parts and palpi very pale brown. Antennae 16- 

 jointed, as long as the body, piceous, the 2nd joint rufescent. Meso- 

 thoracic furrows effaced. Wings subhyaline ; stigma and nervures 

 very pale, the latter indistinct ; radial nervure forming no angle, 

 shortened ; cubital eflfaced ; praebrachial transverse more distinct 

 than the rest ; 2nd discoidal areolet longer than half the prae- 

 brachial transverse ; apical third of the wing entirely nerveless. 

 Legs fusco-testaceous, including the coxse ; 4 posterior femora, tibia?, 

 and tarsi, infuscated, except at the base. Abdomen elongate, nar- 

 rowly oval ; 1st segment linear, its tubercles imperceptible ; extreme 

 base of the 2nd yellow, like the 1st. Length nearly 1 ; exp. 

 2 lines.

^ Black, with the 1st abdominal segment testaceous ; a long 

 pale, irregular patch extends over the following segments. Oral 

 parts and palpi pale. Antennae rather longer than the body,
