ICHNEUMONIN.'E IN THE BRITISH MUSEU3I. 149 



but the head is posteriorly shorter. — The type was captured 

 on Mount Kokanjero to the S.W. of Elgon at 6400 feet oii 

 8th August, 1911, in Uganda. 



3. GLAUCOPTERUS, Sp. n, 



A somewhat dull and evenly punctate-shagreened, black male 

 Avith the laterally carinate scutellum more shining; front tibife 

 alone internally whitish ; wings flavescent. This might well be 

 the alternate sex of the last species, with which the sculpture and 

 colour mainly accord, were it not that the mandibles are rufescent, 

 the metanotal areola and costulte are strong, the apophyses 

 wanting, the abdomen subcyaneous with gastrocoeli deeply im- 

 pressed though naiTower than the substriate intervening space, 

 and the wings deeply clear flavescent with only their apices 

 infumate, the radix and costa, stigma and nervures clear flavous, 

 and the lower basal nervure distinctly postf ureal. Length, 13 mm. 

 c? only. — Yeiy similar, superficially, to the males of my Fimpla 

 glaucojMra (Revis. Ichn. iii. 1914, p. 68) from Uganda and 

 British E.Africa. — Taken on a plateau of Mount Mlanji at about 

 6500 feet on 1st May, 1910, in Nyasaland. 



Leptothecus. 



Head with the clypeus apically truncate and labrum prominent ; 

 cheeks usually strongly buccate. Anteniue broadly pale-banded and 

 not considerably dilated beyond their centre, Thoi'ax unusually 

 cylindrical ; metathorax large and distinctly longer than broad, 

 apically somewhat straight and abruptly declivous ; areola 

 elongate-hexagonal, fully twice longer than broad, apically trun- 

 cate and often basally incomplete ; apophyses spinate. Scutellum 

 deplanate. Abdomen slender, longer than head and thorax, 

 apically narrowed from base of fourth segment, with seven visible 

 dorsal segments ; petiole slender and elongate, becoming gradually 

 a little explanate towards its ajDex ; pygidium large and two- 

 thirds the length of the penultimate ; ventral plica obsolete ; 

 terebral valvular strongly prominent, remote from hyiDopygium 

 and as long as the white-marked two apical segments. Legs with 

 tarsi spinose ; hind legs much the longest, with their tibiae basally 

 constricted. Wings with areolet pentagonal and constricted 

 above ; nervelet distinct. 



In his erection of this genus, Cameron (Entomologist, xxxvi. 

 1903, p. 240) correctly places it in the Oxypygini, and an exami- 

 nation of the genotype enables me to emend it slightly, as above 

 given. Its author considered that it " may be known by the 

 elongated spined median segment, with its elongated coffin-shaped 

 areola, confluent with the lateral arese at the base ; by the long 

 projecting ovipositor ; and by the smooth impunctate abdomen, 

 with its small gastrocceli." It has the facies of Stenichneumon 

 Thorns., but the face is not apically constricted, the cheeks are 

 buccate in the typical species and the juxta-coxal is entirely
