Hugh Scott: 



There is however but little to add to my former description 

 and figures. The 2nd abdominal tergite of the $ was described and 

 iigured as quite bare on its surface, and this was correct as far as 

 concerned the material then before me. In many of the contained 

 in the larger material it is also quite bare, but in some it bears 

 extremely short fine bristles on the middle part of the disc near 

 the hind margin ; they cover a roughly triangulär area with its apex 

 pointing forwards. The 2 oval chitinous plates representing one 

 of the sternites of the $ (fig. 4b of my 1908 paper) sometimes have 

 the short stiff erect bristles on their surfaces more numerous and 

 covering almost the whole surface, instead of being found only 

 on its posterior part as in the figure referred to : also the transverse 

 chitinous plate (op. cit., fig. 4c) sometimes has short stiff erect 

 bristles scattered over its surface, and not only near its hind margin. 

 It is just these variations from the form described as the type, 

 which are found strongly developed in two $5 from Ceylon collected 

 by Mr. Fryer. 



Among the dried material, 2 <J and 1 $ have a fungus of the 

 order Laboulbeniaceae growing on their abdomens. It appears to 

 to grow chief ly on the pleural region. One has two fairly large 

 groups in the pleural region of the 2nd and 3rd segments, and 

 other smaller groups on the posterior pafts of the abdomen: the 

 other (J has a group on the anal segment near the base of one of 

 the claspers, and smaller pieces on the pleural regions of the 3rd 

 and 4th segments. The $ has a large group more dorsolaterally 

 placed, just behind the posterior margin of the 2nd tergite, and 

 another dorsolateral group near the base of the anal segment. 

 A $ of this same species collected in Ceylon by Mr. Fryer, and 

 preserved in alcohol, also bears two groups of this fungus, one on 

 either side of the abdomen: they are ventrolaterally placed, just 

 posterior to the two oval chitinous plates representing the (?) 

 4th sternite. Possibly the fungus is more pleural in position in 

 the (J, owing to the soft connexival membrane being there exposed 

 between the harder tergites and sternites: while in the $ abdomen, 

 where expanses of connexivum are exposed both dorsally and 

 ventrally, its position may be less restricted. Be this as it may, 

 in these specimens at any rate the fungus does not seem to be 

 attached to the harder chitinised portions. 



The specimens bearing Laboulbeniaceae were submitted to 

 a mycologist, Mr. F. T. Brooks (Demonstrator in Botany in the 

 University of Cambridge). He considers the fungi to be almost 

 certainly identical with the form described by Peyritsch 1 ) as 

 Laboulbenia nycteribiae (== Helminthophana nycteribicc Thaxter 2 ).
