described; they are very pale, transparent, cylindrical, elongated, 

 and bent elbow-shaped on the first third, so that the last two- 

 thirds run parallel with the antenna. The length of these remark- 

 able teeth is 0.035 mm., 

 their breadth 0.005 mm. 

 He only found them in 

 Anophthalmus, and in no 

 other species of Carabidse ; 

 they must resemble the 

 teeth described in Chry- 

 sopa. Our species pos- 

 sesses similar processes 

 (Fig. 277). Similar teeth 

 occur on the maxillary 

 and labial palpi of beetles. Dyticus marginalis possesses at the end 

 of each terminal palpal joint a group of very small teeth, which were 

 also detected in Anophthalmus bilimekii, Melolontlia vulgaris, etc. In
