The Insect Fauna of Van Biemenh Land. 311 



Truncatipenna, but I could not arrange it among any of tlie 

 known genera. An examination of the mouth gave me, 

 at length, an insight into its systematic affinity. I shall 

 speak of it again as the new genus Amhlytelus. 



The group oi Anchomenides numbers six new specimens 

 in Mr. Schayer's collection : of these there are two new 

 species of Anchomemts, — one of the genus Eulepkis, KL, (*) 

 (formerly observed in Africa only), and two different species 

 oi Byscolus Dej., (Loxocre])is, Esch^, found in both America 

 and the East Indies by Dejean. It was classed with the 

 Tnincati])enn(B, but incorrectly so, as an examination of the 

 mouth proves. The relationship to Anchomenus is so close, 

 that the arrangement of a species often depends on the 

 shape of the fourth joint of the foot. The two species 

 described below have one lobe (Lappen), perceptibly longer 

 than the other : they are, therefore, Loxocrepi. A wingless 

 beetle, which forms the new genus LestignatJms, has the 

 shape and the simple feet of the more slender of the Ancho- 

 meni, but it presents also a great anomaly in this sub-family 

 of Carabici, in its possessing strongly-defended mandibles. 



The last collection contained one, but a very interesting 

 species of the family Bt/Uscus : it belongs to the genus 

 Bunectes, — is nearly related to, and jet specifically distinct 

 from, E. griseus. Of this genus one single species, E. 

 griseus, is distributed over all the warmer parts of the 

 old world : two others, E. helvolus and succinctus, Kl., have 

 a very limited distribution ; and a fourth is peculiar to 

 New Holland. 



(*) Klug founded this genus on a species brought from Madagascar : another 

 species was brought from S. Africa by Drege : I saw a third in Copenhagen, in 

 Westerman's and the Eoyal Collecfcions ; it was from Guinea, and was distinguished 

 by its broad and flattened mitenna. Our collection has received a second species 

 from New Holland, through Lhotzky.
