MiOJOPPA. 



Head not broader than thorax, roundly constricted posteriorly ; 

 temples shorter than eyes; face subdeplanate and not discreted 

 from clypeus ; cheeks not short, mandibles gradually constricted 

 to apex, palpi slender and elongate. Antennte stout and not 

 longer than body, broadly white-banded, and beyond their centre 

 compresso-dilated. Mesopleui-a> obliquely carinate above their 

 centre; metathorax gradually and i-oundly curved, with its 

 latei'al carinje entire ; petiolar area parallel-sided, narrow and 

 extending to basal thii'd of metathorax ; areola obsolete, incom- 

 plete, remote from metanotal base; spiracles suboval and thiice 

 longer than broad ; apophyses wanting.- Scutellum deplanate, 

 stoutly carinate laterally to near its centre; postscutellum 

 basally bifoveolate. Abdomen with first longer than second 

 segment, and gi'adually explanate from petiole; second and third 

 segments closely punctate ; gastrocoeli superficial, longer than 

 broad with the intervening space closely striate ; second and 

 third ventral segments plicate ; tei-ebral valvulee exserted, as long 

 as two anal segments. Basal nervure not continuous through 

 median; nervelet indistinct. — I place this genus [of which the 

 above is Cameron's diagnosis (Zeitschr. Hymen, u. Dipt. ii. 1902, 

 p. 391), slightly emended by an examination of the genotype] 

 next the Platyurini, with wiiich the structure of the basal 

 segment is in exact agreement ; and I am not sure that it were 

 not better actually merged therein, in spite of the mandibular 

 conformation. The single known species from India was 

 described, loc. cit., incorrectly as female. 



1. QUADEILINEOLA, sp. U. 



A dull, black and closely punctate male with the legs except 

 basally, antennfe except disc of scape, mandibles except apices, 

 and the palpi fulvous ; facial orbits shortly and tAvo facial vitta;, 

 a small callosity before radices, a dot at apical angles of post- 

 petiole, scutellum except extreme base, and the postscutellum 

 flavous. Clypeus apically truncate and a little reflexed ; frons 

 and face closely punctate and pale pilose ; areola shoi't, semi- 

 circular, and apically incomplete ; scutellum shining, sparsely 

 punctate, and subconvex ; gastrocceli small and valvula? luteous ; 

 coxje and trochanters black ; taivsi simple ; areolet very broad 

 above; radius sinuate. Length, 11mm. J only. — The sculp- 

 ture and outline are similar to Craticlmeimion annulator Fab., 

 rather than Platylahus pedatorius Fab., both black males of like 

 form and structure ; the distribution of the pale marks is 

 peculiar. — The type was taken at Deelfontein in South Africa 

 about 1903 by Col. Sloggett.
