jgg [September, 



niiiterial to tlie Bureau, states {in lit. O.vii.lO) that the tubes were 

 recovered by himself from the lloor of a building at Movogoro after the 

 place had been occu])ied by our troops. 



From the material so fortunately preserved several new species will 

 shortly be described, but in the present paper I wish only to bring for- 

 ward the following peculiar and very distinct Fig-Insect. 



Fam. AGAONIDAE. 



Subfam. Agaoninae. 



Alfonsiella, gen. nov. 



Head uorraal for the group ; not remarliably longer than broad; antennae 

 11 -jointed. Scape triangularly produced ventrallj' ; pedicel without appressed 

 jiointed scale-like sensoria; third joint simple, apically bluntly rounded; 

 sensoria of funicular joints short, in a subapical whorl, each giving rise to a 

 long curved tubular process; the joints themselves largely membranous 

 towards tlie apex beyond the sensorial ring. Mandibles bidentate, not fused 

 with the appendage, which is narrow and stout; its transverse ridges not 

 minutely denticulate. Pronotura entire. Wings with the postmarginal short 

 and obsolescent ; and the radius nearly rectangidar to the costa. Abdonnnal 

 steruites shortly excised postero-niedianly, except the 7th, which is nearly 

 divided ; ovipositor long. 



Genotype, A.Jimhriata, sp. n. 



The condition of the postmarginal at once separates this genus from 

 any other group of African Agaoninae, except Allotriozoon Grandi 

 (2 spp.). From the latter it may be known by (a) the peculiar sensoria 

 on the funicle, (h) the mandibular dentition and simpler structure of 

 the appendage, (c) the labial chaetotaxy, and {d) inclination of the 

 radius. Its relationship to JEisenieUa Ashm. (1906), Pegoscapiis Cam. 

 (1906), and YaleniineUa Grandi (1919) — all neotropical — is also close 

 and apparent ; but in all these the pedicel is armed with numerous sharp 

 rellexed sensoria, the 3rd joint is complex (/. e. with pointed and articu- 

 lated appendage), and the funicle of the normal Blastophagine type. 



Superficially AlfonshUa is very like Agaon Dalm., but a more 

 particular examination shows its affinities lie, on the whole, with 

 Blastopliaf/d Grav. sens. sir. 



AJfonsiella fimhriata, sp. n. 

 (5 . Unknown. 



§. A light-coloured species (but see below). Head darker than any 

 other part of the body, blackisli-brown in colour; pedicel, scape, and legs 

 lightest in tone and coucolorous. Funicle hardly darker. Thorax and abdo- 

 men intermediate in colour between the legs and head, the tergites darker 

 slightly than the sternites. Sheath of the ovipositor nearly as dark as the
