88 Orthoriliapha brachycera. 



Fabricius has no species directiy recorded from Denmaric. Zetterstedt 

 in Vol. I, 1842. has eight species, sent to hini from Stæger: T. 

 hovinus, autumnalis, bromius, luridus, rusticus, C. ccecutiens, relictus 

 and sepulchralis, and in Vol. VIII, 184'.) he adds one more, H. longi- 

 cornis = italica, liius in all nine species; of these T. hovinus is un- 

 certain with regard to which species is exactiy meant. He thus knew 

 nine species eight of which are sure. — In the present paper 23 species 

 are enumerated.

Species of niiddle size, niostiy of hlack coiour with more or less

 than the Iower; the eyes golden green with purplish spots. Three 

 ocelli present. Proboscis as long as the head is high, the labella not 

 reaching half the length of the proboscis, moderately broad. The 

 mandibles and niaxillæ are long, pointed, chitinous blades, the former 

 are the broadesl and as a rule a little serrated on the inside at the 

 apex — in C. riifipes the mandibles are long and sharply pointed, very
