ECUTnilOMOKl'JIA. 101 



parallel-sided, eveuly and distiiictl_y punctate, black, with the 

 apices of all the segments briolit liavous, glabrous aud elevated ; 

 the basal segment glabrous throughout, constricted before its base 

 and not deeply canaliculate ; basal angles of the following black 

 and obliquely incised ; seventh and eighth segments entirely 

 castaneous and the latter disc-ally emarginate ; terebra half the 

 length of tlie abdomen, stout, with the black valvular internally 

 setiferous. Legs stout and fnlvous, with the strongly curved 

 claws blackish, but not basally lobate ; anterior legs entirely 

 tiavous ; the hind cox* and trochanters concolorous, the latter 

 always with their under and external surfaces, and a more or less 

 broad streak above, deep black ; hind femora not impressed above. 

 Winys exactly as in the preceding species, but with the costa and 

 stigma usually castaneous. 

 Le>u/th 7-18 millim. 



This species is so very closely allied to the last-described, that 

 I for long hesitated to accord it specilic rank ; but, in the sixty- 

 seven species I have examined, all have the hind coxre distinctly 

 black-marked and the abdomen deep black with only the apical 

 margins of the segments pale, whereas in the former the abdomen 

 is mainly rufescent or at most brunneous, w ith very indefinite 

 bands, and the cox* immaculate. 



The male of this species is remarkable for the very nodose base 

 and apex of the flagellar joints ; its hind femora are occasionalh'', 

 and the hind tarsi always, blackish, and the thoracic black markings 

 are, perhaps, a little less profuse than are those of the female. 

 The size of both sexes is exti*emely variable. 



No doubt can remain respecting tlie synonymy of Cameron's 

 two species ; the types of both are in the British Museum, and 

 I have carefully examined them : the wonder is that one man 

 could have twice described so distinct an insect. I have seen 

 another large female, labelled '• ty|)e " of Chnj^opimpla omatipes 

 by Cameron also, in the Oxford Museum. 



I have seen two males, which differ in no way from E. notu- 

 ■latoria excepting in the total lack of all alar infumescence. These 

 appear worthy of a varietal (possibly specific) name, and I have 

 pro])osed to term them var. inmiaciilata. E. macuUpes, Cam. 

 -(Journ. Str. Brcli. R. Asiatic 8oc. 1905, p. 121), from Jiorneo, 

 the type of which I have seen in the British Museum, differs 

 only in its somewhat more elongately petiolate areolet, aud should 

 be included among the synonyms of the present species. 



This is one of the most abundant of Indian Pimplin.t:, at least 

 in the central and southern districts, though the late Col. C. T. 

 Bingham captured but two females, both at 8ikkim, between April 

 and June lUUO. Our earliest record is represented by a female 

 in the British Museum, taken l>y Capt. Laing in October 1867 

 in Oudh, in Northern India. Cameron's species was fii-st described 

 from the Khasi Hills of Assam, and I have seen the type of both 

 sexes in the British Museuu), where are several other examples 

 from the same locality. In the Piisa collection is a very long
