174 PERCY SLADEN TRUST EXPEDITION 



cubital nervure broadly arcuate at apex of the wanting areolet ; intercubital nervure very 

 short ; brachial cell short and broad ; upper basal emitted from median some distance 

 before lower basal nervure ; neuration of hind wing very imperfect and apically entirely 

 wanting. 



11. XantJwcharojJS primus, sp. n. 



A pale flavous species with the eyes, ocelli, centre of occiput, antennae above except 

 at their apical third, three mesonotal vittge, a mesopleural line, base and extreme apex of 

 metathorax, scutellum, base of all the abdominal segments broadly and centi-e of first, 

 with lines on the hind legs, black. Face slightly prominent, the apically infuscate 

 mandibles weak with the lower tooth much the smaller. Flagellum jDilose, apically 

 subclavate and brunneous, paler before the black apex. Thorax strongly and evenly 

 punctate ; metathorax very short and declived throughout, with only the strongly sinuate 

 basal transcarina traceable ; lateral cost^e distinct. Abdomen pilose and strongly nitidulous, 

 cylindrical and not compressed ; anal styles slightly exserted. Legs not slender, hind 

 calcaria fully half length of metatarsus. Wings broad, hyaline, with stigma piceous and 

 all the nervures dark. Length, 5^ mm. $ only. 



A remarkable insect of the flavescent Oriental type, such as Xanthopimpla, 

 Xanthexochus and Xanthocamjwjilex. 



Mahe ; the single male was captured near Morne Blanc, in 1908.

12. Diodes vulgaris, Mori. 



Diodes vulgaris Mori., Fauna of British India, ined. (MS.) 



A black species with the abdomen except basally, the scape beneath, mouth and all 

 the legs, red ; the metathorax coarsely sculptured, grey-pilose, with distinct arose ; the 

 basal segment parallel-sided with its apex nearly sphserical and apically constricted ; the 

 areolet obviously wanting and brachial cell subparallel-sided. Length, 6 — 7 mm. 



It is hardly necessary to give a more detailed description of this distinct species, 

 which is instantly known by the brilliantly red scape, black -dotted above, and the peculiar 

 structure of the basal segment, since such will appear in my forthcoming volume of the 

 Fauna of India. 



The connection between the fauna of these islands and the Oriental fauna, rather 

 than that of the Zanzibar Coast, is well illustrated in the capture of this Bengalese insect 

 in three of the Seychelles Isla,nds. Mr Hugh Scott took half a dozen females on the 

 marshy plateau of Mare aux Cochons in August and September*, 1908, on Silhouette; in 

 the Coco-de-Mer forest in the Vallee de Mai on the Cotes d'Or Estate at the end of the 

 latter month, on Praslin ; and at an altitude of between eight hundred and a thousand feet 

 at the Cascade Estate, on Mah^. 



* A single ? of the present, or an allied, Campoplegid genus was captured in Silhouette (Seychelles) 

 at the Mare aux Cochons during September, 1908. This is, however, in poor condition and I do not 

 feel justified in bringing forward a new species upon incomplete material in so difficult and obscure 

 a group of insects. — C. M.
