VARIETIES. 113 



contrary, the ninth joint is not longer than the five preceding 

 joints together ; the tenth is shorter, but the eleventh is as long 

 as the ninth. 



The Anohium pusillum of Gyllenhal seems to be very 

 nearly allied to the preceding species, appearing to differ in its 

 small size, (" Cryptophago cellari fere minus, angustius,") 

 black colour ; (the legs and antennae being however obscurely 

 ferrugineous, as in the English specimens ;) and habitat " in 

 frondibus Abietis." 



From what has been observed respecting the variation in 

 the length of the terminal joints of the antennae in the sexes, 

 taken in connexion with the peculiarities observable in the 

 antennae of other species, it is evident, either that the genus 

 Dryophilus (established chiefly upon the great length of these 

 terminal joints) must sink into Anobium, or that some other 

 species of the latter genus must be introduced into it, or must 

 be formed into sectional divisions of at least equal value with it. 



In the typical species of Anobium^ the last three joints of 

 the antennee are comparatively short, compressed, and gradually 

 widened towards the tip, scarcely any difference being ob- 

 servable in the sexes. In Anob. castaneum they are less 

 incrassated ; in Anob. abietinum, the antennae of the males are 

 " lotigitudine corporis" with the intermediate joints gradually 

 elongated, so that the ninth joint is scarcely longer than the 

 eighth; the two terminal joints are however longer, but 

 scarcely thickened. In the female these organs are shorter, 

 and the three last joints broader, than in the males ; the inter- 

 mediate ones being also longer than in the other species ; 

 whilst, in Anob. moUe, the males have antennae about half the 

 length of the body, very slender, the intermedial joints longer 

 than in the true Anobia ; the three last joints not thicker than 

 the preceding, and occupying about half the entire length of 

 the whole antennae. In the females, the last three joints are 

 shorter and more thickened. 



P. aS". to the Notice of Dryophilus. — Since the above ob- 

 servations were written, Dejean has published the second part 

 of his Catal. des Coleopt., second edition; in which he gives 

 Dryoph. anobioides as an anobium, considering it at the same 

 time as synonymous with the Anobium pusillum, noticed 

 above. J. O. Westwood.
