4. Echthromorpha rufa, Cameron. 



Echthromorpha rufa Cam., Trans. Linn. Soc. ser. 2, Zool., xii. 1907, p. 80, ^$. 



This large and distinct species appears most closely allied to E. (Stagnopimpla) 

 hyalina, Sauss. Grandid. Hist. Madagasc. xx. pi. 16, fig. 1, to which Cameron makes no 

 reference, according to Krieger's description of both sexes (Mitt. Zool. Mus. Berlin, 1909, 

 p. 327), though the markings are far more uniform. It is certainly not Brulle's Pimpla 

 macula, nor its variety vittata, found in Mauritius and Reunion, as indicated by Cameron. 



I have seen the single typical pair, described from Mahe, where they were taken in 

 1906, and these are in every way co-specific with sixty examples captured during the 

 later expedition in Silhouette and Mahe. Those from the former island were secured in 

 the high forest near Mont Pot-a-Eau, mostly at about 1500 feet, in August 1908 ; they 

 were common on the marshy plateau of Mare aux Cochons at about a thousand feet during 

 that and the following month ; and a female and several small males were taken in the 

 lower cultivated country in September 1908. On Mahe, it was noted on seven occasions 

 at Cascade Estate, between eight and fifteen hundred feet, during January and February, 

 1909 ; near Morne Blanc at about a thousand feet in November, 1908 ; and on the slopes 

 of Morne Seychellois between one and two thousand feet on the fourth of the following- 

 February. It is the commonest and most conspicuous Ichneumonid of the Seychelles 

 Islands. 



Xanthopimpla Saussure, Grandid. Hist. Madagasc. 1892, xx. PI. xiii. 



5. Xanthopimpla eous, sp. n. 



A distinctly red, and not flavescent, species with no black markings and the 

 metanotum glabrous throughout. Head with the eyes and ocellar region alone black. 

 Antennae about length of body, deep black with only underside of scape and pedicellus 

 rufescent. Thorax glabi'ous and strongly nitidulous with notauli deeply impressed though 

 not extending to disc, sternauli strong and entire ; metanotum glabrous with no carinjB ; 

 only the lateral costse distinct, extending from near posterior radices to the hind coxa3 ; 

 spiracles elongate and large ; apophyses wanting. Abdomen immaculate and very finely 

 punctate with the transverse impi-essions on segments two to six crenulate ; terebra stout, 

 deep Ijlack, straight and hardly double length of the basally impressed first segment. 

 Legs unicolorous with the hind claws strongly curved and shorter than their black pul villi. 

 Wings an)ple and evenly a little infumate throughout ; stigma, nervures and radius deep 

 black ; basal nervure subcontiiuious ; areolet small, transverse-quadrate and distinctly 

 a little petiolate ; nervellus strongly postfurcal and intercepted at its upper fourth. 

 Length, ? 10—12, ^ 5—8 mm. 



The deep black antennae and nervures contrast conspicuously with the uniformly pale 

 body. It is related in its deficient metanotal sculpture to X. tigris, Krieger (Sitz. Nat. 

 Ges. Leipzig, 1899, p. 75), but in all other respects almost exactly resembles my Indian 

 X. immaculata ; it cannot, I think, be Holmgren's Pimpla citrina (Eugen. Kesa : lus. 

 1868, p. 404), recorded from Mauritius. In the present collection it was mixed with 

 Echthromorpha rufa, to which it betirs a strong superficial resemblance.
