terior margin of some of the segments. Last abdominal segment of male 

 quite long; the superior appendages short, divaricate, black, not half the 

 length of the segment.

Brachynemurus 4-punctatus Currie. 



This species is very constant in markings, as Mr. Currie has 

 already noted ; however, I think it is closely allied to the other 

 species by the structure and general plan of markings. 



EXPLANATION OF PLATE III. 



1 . Brachynemurus assimilis, inter-antennal mark and superior 

 appendage of male. 



2. Brachynemurus carrizonus, inter-antennal mark and su 

 perior appendage of male. 



3. Brachynemurus dissimilis, inter-antennal mark and su 

 perior appendage of male. 



4. Brachynemurus ferox, pronotal marks and superior ap 

 pendage of male. 



5. Brachynemurus texan?ts, pronotal marks. 



6. Brachynemurus texanus, superior appendage "of male.

The paper was discussed briefly by Mr. Currie. He men 

 tioned the fact that many species which differ widely in other 

 respects often have very similar anal appendages and, vice versa, 

 there are some species which resemble each other very closely 

 except as regards the appendages. He said that, according to 

 his own observations, there is considerable individual variation, 

 in some species, both in the length and shape of the inter-antennal 

 marking. Mr. Banks replied that, though there is some varia 

 tion in length, he has found the shape fairly constant in the 

 species he has studied. The paper was further discussed by 

 Messrs. Schwarz and Gill.
