NEW BRITISH SPECIES NOTICED IX I860. 67 



Lincoln, and recently bv Mr. Waterhouse in the Crystal 

 Palace at Sydenham. 



Two specimens kindly given me by Mr. Wollaston, and 

 which have been referred by INI. Motschulsky to the X. in- 

 cisus, Mannerh., appear to me to coincide better with the 

 latter's description of i. carinatus ; in L. excisus the thorax, 

 it would appear, is shorter, the elytra longer (more than 

 thrice as long as the thorax), and the longitudinal ridges on 

 the thorax very divergent. 



15. Heterocerus rectus, Waterhouse, Trans. Ent. Soc. 

 Ser. 2, V. 168 (1859). 

 '^ H.fossor, V. Kiesenw. var?" 



The differences which Mr. Waterhouse thinks will be 

 found to exist between his insect and H.fossor, v. Kiesenw., 

 when specimens of the same sex are compared, are so slight, 

 that it appears to me it would have been more prudent to 

 postpone the imposition of a new name until a comparisDU 

 had been made. 



** Ten specimens from North Wales ?" 

 I believe these examples are supposed to have been taken 

 by the Rev. F. W. Hope. 



16. Heterocerus fusculus, v. Kiesenw.; Waterhouse, 

 Trans. Ent. Soc. Ser. 2, v. 166 (1859). 

 Seterocerus fusculus, Y. Kiesenw. in Germar's Zeitschr. 

 f. d. Entom. iv. 220, 17, T. 3, f. 11 (184.3); Eric* 

 Naturg. d. Ins. Deutschl. iii. 549, 9 (1847). 

 In its elongate depressed form and the disposition of the 

 markings on the elytra yerj similar to Het. hemqatus, Panz. 

 [Faun. Ins. Germ. Fas. 23, f. 13 (1794)], but its smaller 

 size, dull pubescence, more strongly punctured elytra and 

 darker coloured legs, apart from other less obvious dif- 

 ferences, will suffice to distinguish it.
