the protliorax, the smaller size, etc., separate the present species from 

 Dapsiloderns termmalis. The specimens with very slightly widened 

 anterior tarsi and a longer apical joint to the maxillary palpi are 

 assumed to be males. The palpi are wholly flavous in all but one of 

 the examples before me. The Penang examples are taten as the types. 



2. — DapsUoderinws notaticoUis, n. sp. 



Very elongate, narrow, opaque ; black, the protliorax with a transverse 

 rvifous spot or patch on each side of the disc before the base, the elytral humeri 

 indeterminately rufescent, the palpi flavous, the tijis of the tarsi testaceoiis ; 

 clothedswith extremely fine pruinose pubescence ; the entire surface very densely, 

 minutely punctulate, the minute punctures on the elytra transversely confluent, 

 the base of the latter strongly transversely asperate. Antennae long, joints 

 3-10 extremely broad, serrate, sub-equal in length, 11 narrower than 10. Pro- 

 thorax broader than long, the sides rovmded anteriorly and sub-parallel towards 

 the base, the latter bisinuate, the hind angles rather obtuse, the disc foveate in 

 the middle before the base. Elytra without definite costae, the suture closely, 

 transversely asperate towards the apex. Length 6^-Ti, breadth li-lf mm. ( $ ?) 



Hab. : Borneo, Mt. Matang, W. Sarawak (G. E. Bryant). 



Two specimens : one captured in December, 1913, the other in 

 February, 1914. Separable from the variable B. quadricostatus, 

 which has been taken by Mr. Bryant at the same locality, by the non- 

 costate elytra end the entirely black body — the two red spots on the 

 prothorax and the faint reddish humeral patch excepted. It is scarcely 

 possible that D. notaticoUis can be the $ of D. quadricostatus ?

BRITISH DIPTEBA.

In studying the works of the older entomologists, one cannot but 

 be struck by the contrast between the two schools : the real naturalists, 

 such as Reaumur and De Geer, and the mere nomenclators, such as 

 Linne, Fabricius, and Meigen. The latter, no doubt, did a most useful 

 work, but it is to the former that we have to turn for information con- 

 cerning the life-histories of insects. The latter do not seem to have 

 been interested in these aspects of their science, and although they 

 frequently adopted the names of the former, they were often, through
