66 PARTIAL ORISMOLOGY. 



are pectinated antennae., whose joints are very short , but the processes 

 are very long and flat, and consequently lie close together. BIFLA- 

 BELLATE (biflabdlalce) , when both sides of the joints send forth such 

 processes. 



BRANCHED (ramoscp}, when some of the joints only send forth pro- 

 cesses upwards (PI. VII. f. 15). This form should, by rights, be 

 placed under the following head ; but as they are in general filiform 

 antennae which are furnished with such appendages, and they con- 

 sequently bear great resemblance to the preceding forms, we have 

 preferred introducing them here, among those they were most like. 



FORKED (furcates, PI. VII. f. 16), is when throughout its whole 

 length it is separated into two branches or prongs (Schizocerus, 

 Lat.). 



b. Unequal Antennae. 



THE inequality of antennae proceeds chiefly from the differing 

 form of their second and last joint, on which account they demand 

 especial notice. Very generally the first or second joint is much 

 longer than the following, and is also not placed in the same direction 

 with them, but the third joint is inserted laterally upon the second at 

 a right angle. Such antennae are called BROKEN (fractal), or GENICU- 

 LATE (geniculatte, PI. VII. f. 17) ; and the long joint is distinguished 

 as the SCAPE (scapus, the same, a~), and the following as the BRANCH 

 (flagelhim, the same, b). 



The branch of such geniculated antennae is frequently merely cylin- 

 drical or filiform (Apiuria, fig. 17) ; in other instances, on the contrary, 

 the joints of the branch differ again from each other. We thence dis- 

 tinguish many forms which are also found in not geniculated but 

 merely unequal antennae. The following are of this description: 



CLAVATE (clavatce, PI. VII. f. 18), when the joints become gra- 

 dually broader, so that the whole organ assumes the form of a club 

 (Silpha). 



CAPITATE (capiiatce), or such whose terminal joint forms a large 

 round knob. If the knob is formed by but one joint, it is called SIMPLE 

 (capitulum solidum}; but when composed of several, it is called, in 

 contradistinction, COMPOUND (capitulum composition, PI. VII. f. 19, 

 Necrophorus). PERFOLIATE (cap. perfolialum) , when the joints of 

 the knob slightly stand off from each other all round (Hydrophilus,
