VARIETIES. 325 



23. Carabus exasperatus. — This insect is not Carabus 

 violaceus. I have seen it alive in the Isle of Portland, and 

 it is different from the C. violaceus I have seen elsewhere. 



J. C. Dale. 



24. Lasioglossum tricingulmn. — This is certainly a different 

 genus from Halictus, which may be seen by comparing the 

 dissections in Curtis's plate. 



J. C. Dale. 



25. Cerapteryx Hibernicus. — This is, I believe, Chareas 

 Graminis ; but it is, at least, a fine and large variety, and 

 Mr." Curtis is fully justified in his observations ; he merely 

 says, " it may be a new species." 



J. C. Dale. 



26. Hippobosca Equina. — In the Entomological Magazine, 

 you have said that Mr. Curtis's figure of this insect is much too 

 highly coloured ; I beg to say that I have a specimen of the 

 insect much more highly coloured than Mr, Curtis's figure. 



J. C. Dale. 



27. Hister ^-maculatus. — You are wrong in saying that 

 the Hister 4^-maculatus, of Curtis, is the Hister sinuatus 

 of authors, and Mr. Curtis is right, for it certainly is the 

 H. 4-maculatus of Linne, of Gyllenhall, and of Paykull. H. 

 sinuatus does not belong to the same division ; it has not, what 

 has been termed, a marginal stria on the elytra, and is a 

 smaller insect ; its thorax is semiovate and truncated before, 

 so that the sides are rounded, and the base very much broader 

 than the fore part, and the apical tooth of the anterior tibiae is 

 bidentate. Does this, I ask, agree with Mr. Curtis's descrip- 

 tion or figure ?

28. Smiera Mac Leanii. — Dalman, in describing C. Mela- 

 tiaris, $ , says " There is a white spot on each side between the 

 eyes ; the anterior tibiae are rufescent, pale at the base on the 

 outside : thighs with a somewhat apical white lunule on both 

 sides." If Dalman's insect, of which he took twenty specimens,
