 elytra longer than pronotum, rather robustly not densely punctated; 

 abdomen especially at middle sparsely punctated; hind tibiae with a 

 single projecting spine at tip. L. 5-6 mm. 



In the <? the posterior margin of seventh ventral abdominal joint 

 is at middle angularly produced. 



On ocean beaches and at salty lakes in Middle Europe; in this country 

 so far only found on the west coast of Sleswick, in marshy clay, especi- 

 ally where the coastal margin forms into small low brinks. Its tunnels 

 run more than 24 inches in depth; can be found in great numbers in spots 

 and (accd.to Prof. I. Schiodte) often in company with Coryphium longicor - 

 ne ( ansusticolle ?).

Very closely allied to and like bicornis , from which it mainly is 

 separated by, that elytra are pale brownish-yellow with narrowly dark- 

 brownish suture and legs likewise lighter brownish yellow, that prono- 

 tal fore-corners are not protruding, but rectangular, . and that the el- 

 ytra is more isolated and finer, posteriorly feebly punctated. In the 

 O the horns of the head are acute, furthermore it i6 as a rule smaller 

 than bicornis. L. 3.8-5 mm. 



With certainty only known from this country, where it is distrib- 

 uted and found both at the strand and at inland lake shores (Amager, 

 Nys^, Pedsle, Maribo, Esbjerg, Harbo/5re, Blokhus). - Bl. hinnulus F,r.
