tion except the rather primitive sketch accompanying the account of Mr. 

 N. H. Corquodale on the infested horns of a hartebeest in Nature, Vol. 

 58, 1898, p. 140. This sketch differs in some particulars from the present 

 specimens; it figures the larvae tubes as single and coming from all parts 

 and sides of the horns, while in the present specimen they are more or less 

 bunched and matted together, though a feAv single tubes were found; 

 more important than this, the present specimens were confined to the side 

 of the horn, which had evidently been toward the ground, and besides 

 particles of the horn they had incorporated in them a good proportion of 

 earth. The explanation of this may be that Mr. Corquodale's horns have 

 become infested while or just before they were boxed for shipment and 

 that the larvffi constructed their tubes in different directions, due to the 

 varying position of the box, which, was no doubt frequently changed during 

 transit. 



While the present cases presumably are the work of Tinea vastella 

 Zellar, which seems to be common everywhere in Africa, and which is 

 credited with all the recorded infestations from Africa, it should be 

 remembered that other species of the genus have similar habits, and that 

 more than one species may be involved. Stainton described one species, 

 Tinea orientalis, bred from horns in Singapore, and the writer has seen 

 similar work in horns of domestic cattle lying on the ground at Fajardo, 

 Porto Rico ; in fact the habit is parallel with and very similar to those of 

 the common tubemaking cloth moth Tinea pellionella Linne.
