118 STATES OF INSECTS. 



globules, which are often not visible but under a power- 

 ful lens, is so different from that of the eyes of a butter- 

 fly or moth, or other perfect insect, that it has been 

 doubted whether they actually perform the office of eyes, 

 but without reason. They occupy the usual station of those 

 organs, being situated in many instances upon a protube- 

 rance which appears to incase them ; and seem of a con- 

 struction closely analogous to that of the eyes of spiders, 

 and the stemmata or ocelli of Hymenoptera, which have 

 been satisfactorily proved to be organs of vision. In the 

 larva of a moth not yet ascertained to exist in this coun- 

 try, Attacus Tau, and probably other species, the eyes, 

 after the skin has been changed a few times, are no longer 

 to be seen a . 



Anlennte. Most larvae are provided with organs near 

 the base of the mandibles, which from their situation and 

 figure may be regarded as antenna?. Fabricius has as- 

 serted that the larvae of the saw-flies ( Tenthredo L.) have 

 no antennas; but in this he was mistaken, for though 

 very short, they are discoverable in them, as he might 

 have learned by consulting De Geer b . In the majority 

 of Neuropterous larvae, they almost precisely resemble 

 those of the perfect insect. In all the rest they are very 

 different. The antennae of Coleopterous larvae are usu- 

 ally either filiform or setaceous, consisting of four or five 

 joints, nearly equal in length. Those of Lepidopterous 

 larvae are commonly conical, as are those likewise of 

 Chrysomela and Coccinella &c. amongst the Coleoptera, 

 and very short, composed of two or three joints, of which 

 the last is much thinner than the first, and ends in one or
