which one is lateral and, beginning close under the humeral 

 prominence, extends in a nearly straight line to the external 

 apical angle ; the second, just above this, is very feeble, soon 

 disappears, and seems to be a continuation of the humeral 

 prominence ; the third is placed about a millimetre higher up 

 than the first and almost on the edge of the disk ; along the 

 inner side of this carina is a row of punctures, between it and 

 the middle carina is a second row of larger and more distant 

 punctures, while just beneath the first or lateral carina, near 

 the middle of its length, is a short row of very small punc- 

 tures. In S. nigricornis the arrangement of the carina? and 

 punctures is somewhat the same, but the lowermost or lateral 

 carina of each side is less prominent, especially anteriorly ; 

 the median carina is much more distinct and is plainly seen 

 to be a continuation of the humeral prominence ; while the 

 third or discal carina is much feebler. The punctures too are 

 much fewer in number and placed more widely apart ; but in 

 this respect S. nigricornis is subject to vary. In the type 

 specimen of Fabricius there are only four or five punctures in 

 each row, while in other specimens twice this number is 

 reached. In S. nigricornis the legs and underside of the body 

 are generally greyish ; in the present species they are dis- 

 tinctly fulvous, with the tarsi on their upperside and the abdo- 

 men and breast partly black. 



From Mr. Thomson's too short diagnosis of S. lateralis I 

 am quite unable to determine his species. It is from N. 

 India. The species just described may possibly be the same 

 or a variety of it.

VIII. — Note on Tealia tuberculata and T. crassicornis. 

 By G. Y. and A. F. Dixon. 



In a paper published in the ' Journal of the Marine Biological 

 Association ' (vol. i. p. 205) Mr. J. T. Cunningham endea- 

 vours to set up Tealia tuberculata (Cocks) as a species distinct 

 from Tealia crassicornis (Miiller). Perhaps we may be
