44 COLEOPTEKA. 



The typical genus Buprestis, Linn., is most numerously repre- 

 sented in the Mediterranean district and in North America. B. 

 Octoguttata, Linn., a South European species, is steel blue, with 

 yellow spots. 



Stigmodera, Esch., is a very large Australian genus, including a 

 number of pretty species of small or moderate size, generally black, 

 more or less varied or spotted with red. 



Agrilus is another very extensive genus, which has represen- 

 tatives in all parts of the world. The species are about a quarter 

 of an inch in length, and of a blue, green, or brown colour ; one or 

 two are found in England. The smallest of the Buprestidce belong 

 to the genus Trachys, Fabr., which is well represented in Europe, 

 the East Indies, etc. The European species are black or brassy, 

 and several do not exceed one-twelfth of an inch in length. 

 The allied Brazilian genus Brachys, Sol., is of a more oval form 

 than most of the family. 



FAMILY II. Trixagidce. 



Body cylindrical, not fitted for leaping ; eyes round ; antennae 

 inserted at the lower border of the eyes, filiform or clubbed, and 

 received into cavities of the thorax. 



The typical genus of this small family is Trixagus, Kug. 

 (Throscus, Latr.), represented in Europe by a few brown or reddish 

 species of very small size (the largest not exceeding the eighth of 

 an inch in length), which are found among dead leaves, etc. 

 Most of the species belonging to other genera are American. 



FAMILY III. Eucnemidce. 



Body cylindrical, not fitted for leaping ; eyes round ; antennas 

 received into cavities of the thorax, and generally pectinated ; in- 

 serted on the upper part of the head ; larvae feeding on rotten 

 wood. 



Most of the Eucnemidce are insects of small size and dull colours, 

 and are generally found on flowers ; few of the European species 

 exceed one-third of an inch in length. The typical species is 

 Eucnemis Capucinus, Linn., a black cylindrical species, with 

 brown legs, and nearly a quarter of an inch long. Two foreign 

 species may be noticed Fornax Madagascariensis, Cast., a dark- 

 brown beetle from Madagascar; and Pterotarsus Tuberculatus, 

 Dalm., from Brazil, which is red, with black markings.
