INSECTS OF A FORMER WORLD. 577 



very similar to the Elfiter cylindricus, Gyll., and many smaller 

 species, but I have not found a single Buprcstis, although these might 

 readily offer. The Deperditores are, however, not rare, namely, forms 

 resembling Anobium perlinax and An. rujipes. Desmarest found, 

 also, an Atractocerus in amber. A Cantharis very like C. nigricans, 

 Fab., I have seen in the Berlin collection. Among the Heleromera 

 I have hitherto only observed a small Opatrum allied to Op. sa- 

 bnlosum. Germar has described a Mordella (M. inclusa). Of the 

 Tetramera, I detected in the collection at Greifswald the leg of a 

 capricorn-beetle, but no other insect of this family except a little 

 creature very like the Obrium testaceum. The Chrysomelce are more 

 numerous. I saw a small purple shining Haltica, several Crioceris, 

 and a few Gftllerucce. The Bostrychodiee are very numerous, but I 

 could not determine one with certainty. In Greifswald I met with a 

 species of Platypus, and in Berlin with several true Bostrychi and 

 Apata. The Curculios also are tolerably abundant, particularly species 

 of the genera Phyllobius, Polydrusus, Thy Incites, &c., and some forms 

 allied to exotic groups, which I could not more closely determine. I 

 have never observed any of the smaller Curculios, as Ceutorhynchus, 

 Cionius, or Apion. 



The Hymenoptera are very abundant, but I have never observed a 

 Tenthredo or a Urocerus, although both families live especially in woods 

 and feed upon vegetable substances, and the latter, as larvae, bore the 

 stems of trees. But in the Berlin Museum there are several 

 Ichneumonodea, whose generic affinities I have not yet been able to 

 determine satisfactorily. One of them has antennae swollen in the 

 middle like Bassns (Euceros) Crassicornis, Grav. An Evania also, 

 allied to Evania minuta, Fab., is at Berlin and Greifswald. I have 

 not yet observed a Cynips in amber, although I have seen a Sphex that 

 certainly belonged to the genus Pepsis, but which is entirely faded, so 

 that it is impossible to determine the species. It is of about the size 

 of Pepsis lutaria, Fab. ( Ammophila, Kirby), but the thorax is more 

 slender, and the abdomen has not so long a petiole, whence it resembles 

 the American and particularly the African species. Crabros, Scolias, 

 Mutillas, and wasps, I have not found, but I saw a small form of bee, 

 which appears to belong to the South American genus, Trigona, Lat. 

 The ants are the most numerous in this order, particularly true Formicas 

 and Myrmlcce, which have frequently a close resemblance to our native 

 ones. The majority are apterous neuters, which have fallen into the
