176 BRITISH ICHNEUMONS. [Cecidonomus. 



I have seen but two examples of this anomalous species. I captured 

 the type on a very hot day in the Bentley Woods, near Ipswich, on 27th 

 May, 1900 ; and \\'ilson Saunders took a specimen, several years ago, 

 probably at Greenings near East Grinstead, though no locality is attached.

 Thorns. O. E. .x. 970, i ? . Cecidonomus rufiis, Bridg. Entom. 1880, p. 265, ? ; cf. 

 lib. cit. 1883, p. 155 ; Schm. Term. Fuz. 1897, p. 562, ?. 



Head with the vertex somewhat broad and not narrowed posteriorly ; 

 palpi, and in $ sometimes the centre of the mandibles, red ; clypeus 

 incompletely discreted with two apical central teeth ; mandil)les not tuber- 

 culate, cheeks buccate ; frons dull, densely and very finely pubescent ; 

 $ face strongly pilose, and a broad basal mandibular mark, white. 

 Antennae black, slender, filiform and nearly as long as the body ; of $ 

 shorter, with the scape clear white beneath. Thorax finely alutaceous ; 

 pronotum with no central carina ; mesonotum dull, densely and very 

 finely pubescent, with the notauli obsolete ; metathoracic areae entire, 

 areola pentagonal or hexagonal, hardly longer than broad and basally 

 constricted, of $ sub-transverse ; metapleurae nitidulous, petiolar area 

 discreted, apophyses small. Abdomen oblong-ovate, as broad as the 

 thorax, of 9 apically sub compressed ; black, of ? with the second segment, 

 more or less of the first apically and generally the basal half of the third 

 segments, red, the two apical segments more or less distinctly white- 

 margined ; of $ with the incisures sometimes castaneous ; basal segment 

 sub-canaliculate and obsoletely aciculate, with the petiole short, bicarinate, 

 and the post-petiole hardly longer than broad, though twice broader than 

 the petiole; second segment finely and evenly punctate or, in c^, sub- 

 rugosely punctulate and somewhat elevated centrally at the apex ; terebra 

 as long as the abdomen and distinctly deflexed. Legs normal ; red with 

 the hind tibiae not vvhite-banded but generally apically, like their tarsi, 

 infuscate ; $ with the hind coxae black, the anterior and all the tro- 

 chanters white. Wings hardly clouded ; stigma piceous and hardly paler 

 basally, radix and often tegulae white, areolet wanting, nervellus distinctly 

 antefurcal. Length, 4-6 mm. 



Taschenberg says that the $ is very like Hemiteles castaneus, but the 

 areola is decidedly narrow basally, the post-petiole parallel-sided with a 

 shallow furrow, antennae unicolorous and clypeus only sub discreted. 

 Brischke calls attention (Entom. 1880, p. 255) to its resemblance with 

 H. monospihis, Grav. ; and Thomson points out that the female may be 

 known by its slender antennae, which continue black towards the base, 

 the confluent fenestrae, terebra nearly the length of the apically compressed 

 abdomen and by its coloration. The $, is distinct in its short, stout, sub- 

 setaceous antennae, and in having the abdomen nearly totally black. 



Mr. Weston bred three females from the galls of Cymps Ko//ari, where 

 perhaps it was parasitic upon inquiline Aa/kata, in 1878-9 ; and two 

 more of the same sex were captured by Bridgman near Norwich ; it occurs 

 in June. Eaton and Earlham in Norfolk (Bridgman) ; bred in Devon, on 

 14th April, from an unknown host (Bigncll) ; Maldon in Essex (Fitch) ; 

 Dr. Capron took it commonly at Shere, Wilson Saunders at Reigate in
