I have examined six specimens, three of each sex, from France, 

 near St. Servan (Ille-et-Vilaine), where the Rev. R. Godfrey has 

 taken it in great numbers under bark of pine-trees. The species 

 has previously been found only at Arcachon (Gironde) by 

 E. Simon. I have also seen a specimen from Central Italy 

 collected by Mr. Adolf o Ro>.-i. 



This species differs considerably from C. mitseorum, Leach, 

 but has much more affinity with the South American species 

 C. corticum, Balzan, from which it may, however, be distinguished 

 without difficulty among other characters by the more robust 

 tibia. In the South American species too the eleventh tergite is 

 visible from above to a degree, though not quit" so distinctly as 

 in the French species. C. museorum, Leach, has only ten tergites 

 visible from above; in this species the galea of the g is small and 

 acute, and in the $ it consists of only one stemlet, stronger than 

 that of the <$, and with some small teeth in the point. 



Cheiridium museorum, Leach. 



I have seen specimens taken by Mr. Wallis Kew at Rainhani 

 (Essex) under the wall-paper of a deserted cottage.
