NEW BRITISH SPECIES, ETC., IN 1871. 71 



and stronger punctuation on the elytra, which are more 

 acuminate behind in outline. 



There appears to be considerable doubt on the continent 

 with regard to A. atra. 



60. MoxoTOMA 4-DENTATA, Thoms., Opusc. Ent., 333; 



E. C. Rye, I. c, viii, 160. 

 The differential characters given for this insect by Thom- 

 son, as pointed out in the above reference, seem to leave 

 little room for doubting that it is the prior described hrevi- 

 collis of Aube. 



61. MoNOTOMA PARALLELA, Thoms., /. c, 334. 

 Thomson, who does not mention quadricollis, Aube, com- 

 pares his insect with picipes, stating it to be smaller and 

 narrower, with hardly foveolated forehead, longer thorax, 

 which is scarcely at all wider behind than in front, and has 

 the disc more delicately scabrous, and very shallow basal 

 foveolse, and elytra scarcely wider than the thorax but longer 

 in proportion, with parallel sides, more delicately punctate- 

 scabrous, with the interstices scarcely rugulose. These 

 characters so accurately fit Aube's species, that there is little 

 doubt of the two being identical. The points of difference 

 mentioned by Thomson between his parallela and M. lonrji- 

 coUis also tend to the same conclusion.

Mat., &c., 1863, 73; E. C. Rye, /. c, vii, 274. 



Taken by Mr. Champion and myself in the early spring 

 of the past year under dry bark in Richmond Park. Also 

 in Dr. Power's collection.

 on account of discrepancy in colour) referred as above, are
