sufficiently warrant their being organs of touch and later in- 

 vestigations agree with this view. 



The apparently typical, dorsal plates of the fifth abdominal 

 segment of the larvae of Cicindelidae will have to be consid- 

 ered, I suppose, as organs with sensorial functions, but this sup- 

 position is in need of exact observation. They are usually 

 regarded as claspers.^ 



Corpus adiposum. The adipose body does not present any- 

 thing extraordinary. The larger lobes are above and at the 

 sides of the digestive tract, and are dirty-white, presenting, 

 when magnified, roundish globules enveloped in connective 

 tissue. The globules consist of very tender and undulate 

 lamellae. The larger lobes of the corpus adiposum are also 

 enveloped in a sort of tissue, and here and there receive small 

 tracheal branchlets, an arrangement which serves to keep the 

 adipose body in position. 



Numerous roundish, white corpuscles, of a diameter of 0.2 

 to 0.5 mm., are found dispersed over and between all the "inter- 

 nal organs, undoubtedly organic matter secreted from the 

 corpus adiposum through the general transelementation. 



Female sexual orgatis. The cylindroid-oval eggs are appar- 

 ently free, imbedded in the body cavity. In the condition in 

 which I received the specimens, the finer ovarian membranes 

 were wholly broken up. Specimens caught at a difterent season 

 would undoubtedly have been more interesting. I found the 

 eggs of equal size, and vainly searched for less developed ones. 

 There are from three to six eggs in each individual. The 

 length of the egg is about 4 mm., its width not quite 2 mm. 



The brown coagulated deutoplasm, or yolk, has no yolk- 

 membrane. It lies loose and considerably contracted in the 

 hyaline chorion. The two poles of the 

 /rj\ deutoplasm are, in every instance, con- 



U M- <L tracted to one side, which, for conven- 



\:^)""'^ ience, I will call the ventral side (Fig.
