458 Mr. C. J. Gahan on 



extreme anterior and posterior margins, the disk rather 

 thickly punctured, carrying four well-marked impressions, 

 and having a line of ashy-grey hairs along the middle ; each 

 elytron with a line of ashy-grey hairs along the middle and 

 a similar line at the sutural margin ; first joint of the middle 

 tarsus of the male much shorter than the second and having 

 a slight projection underneath, which is somewhat emarginate 

 at the anterior end, forming a kind of hook. In the female 

 the corresponding joint is normal and longer than the second 

 joint. (In the male of A. spurcaticollis the first joint of the 

 middle tarsus is simple, but the tibise of the same legs are 

 bent near the extremity.) 



The above description was written before I had an oppor- 

 tunity of seeing M. Fairraaire's paper and may be allowed to 

 stand, as it supplements his description, in which no mention 

 is made of the sexual differences. The species does not 

 possess the chief distinguishing characters of the genus 

 Chitona, since the head is not prolonged in a distinct muzzle, 

 while the eyes are slightly emarginate in front, with the 

 antennge in close proximity to them.
