Figure 6. Oligota oviformis , larva. Pseudopod and urogomphi. 
The larva of Oligota oviformis is similar to that of O. flavicornis 
Boisduval and Lacordaire as described and illustrated by Paulian 
(1941). The two species differ in that in O. oviformis the “acorn 
seta” of the second antennomere is almost as long as the third seg- 
ment and has no distinct articulation at its base whereas Paulian’s 
illustration of O. flavicornis shows two very small “acorn setae” 
with distinct articulations at the base. In O. oviformis the uro- 
gomphus is an extension of the eighth segment without articulation 
or segmentation. In O. flavicornis it is distinctly two-segmented. 
Pupation takes place in a cocoon in which the pupa is quite loose. 
The cocoon is formed of sheets of silk to which grains of sand 
adhere. In one instance the cocoon was formed in part of several 
sheets of silk extending like short walls perpendicular to the axis 
of the pupa.
