Demopheies.] BRITISH ICHNEUMONS. IQ 



with sometimes the base and apex of their tibiae, iiifuscate ; c^ with anterior 

 coxae and trochanters white. Wings normal, liardly clouded ; radix and 

 tegulae white. Length, 6-8 mm. 



Taschenberg says that this species, which is the Phy^adeuon corritptor of 

 Marshall's 1872 Catalogue, is very like Cubocephalus brevicornis, but that 

 the second segment is not, as in that species, punctate ; the inner orbits 

 are white and the antennae less incrassate ; the conformation of the wings 

 is similar to those of C. nii::riven/ris. 



It occurs in June throughout northern and central Europe, but I know 

 of no specific British records, and it was not recognized as indigenous till 

 1872. There are three males and two females in Dr. Capron's collection, 

 probably captured in Surrey. 



CUBOCEPHALUS, Ratzeburg. 



Ratz. Ichn. d. Forst. ii. (1S48), 121 ; Paiii/iiatkits, Forst. Verb. pr. Rheinl. 1868, 

 p. 185. Stenocryptus, Thorns. O. E. vi. (1874), 603. 



Head cubical, cheeks very broad and temples buccate behind the small 

 eyes ; mandibles somewhat elongate with the teeth of equal length ; clypeus 

 strongly discreted and apically mutic. Antennae of ? not longer than 

 thorax, incrassate ; post-annellus shorter than the slightly excised scape. 

 Abdomen oblong, sub-parallel-sided, of ? apically sub-compressed ; basal 

 segment with obsolete carinae, second densely and very finely alutaceous, 

 longer than the third. Legs stout, calcaria not reaching the centre of the 

 metatarsi ; tibiae mutic. Wings with the areolet pentagonal. 



Thomson says that his Stowcryptus agrees most closely with Crato- 

 crypfus, but that the head is more cubical with much more buccate cheeks ; 

 the antennae are shorter, with the scape as long as the post-annellus and 

 less deeply excised apically ; the abdomen, also, is smaller and nearly 

 glabrous. From Mecocryptus (Demopheles), he says it differs in the 

 apically entire clypeus and larger mandibular teeth, though similar in 

 facies and the form of the head. 



The position of this genus has been a doubtful point ever since its 

 erection by Ratzeburg, who says the female abdomen resembles those of 

 both Campoplex and Xorides ; to the latter it appears related in its pos- 

 teriorly buccate head and short legs, and attention has also been drawn to 

 the similarity of its antennae to those of A/omyia. The male, however, 

 bears distinctly Cryptid facies, and both sexes have the pentagonal areolet : 

 I do not find the position of the petiolar spiracles described. Marshall, 

 in 1872, follows Taschenberg in retaining it in Phygadeuon, and Thomson 

 treats of his sub-genus in the same position. Cuboiephalus is not placed 

 by Forster, though its synonymy with Cy/hceria, Schiodte, Rev. Zool. 1837, 

 p. 140 (given by Ashmead as the same as Lampronota, Hal.) is queried. 

 Ashmead sinks Sterwcryptus as a synonym of Pammachus with no type 

 (the type of tiie former is ttigrivefi/ris, Thorns. O. E. 521) under the Cryp- 

 tinae, and gives Cubocephalus as (juite distinct, also with no type (the type 

 is forlipes, (Irav., cf. Ratz. /oc. a/.), under the Xoridini. ' 'I'he present 

 appears to be the most convenient tentative position for this genus, which 

 Schmicdi'knecht, retaining 'I'Ikjuisoii's name, thinks may also include 

 Ecporlhefor, Forst.
