and of other larvse from the same mating except the ab- 
dominal segment 6. 
In 1927 Cappe de Baillon wrote a very excellent book 
which concerned itself entirely with teratology or mon- 
strosities found in insects. While the principle part of the 
work deals with a study of Carausius morosus Brunner, a 
phasmid, one that is very prone to irregular development, 
there is included a 382-title bibliography. Practically all 
of these references refer to adult irregularities, probably 
because those forms are the ones found in collections. Most 
of these malformations take place in the pupal reorganiza- 
tion. How much larger the list would be if larval anomalies 
such as the one here reported were more often found! In 
this whole list of references only one deals with elaterids. 
That one is by Bastine 1 and concerns itself with an anten- 
nal irregularity in an adult of Melanotus rufipes Herbst 
in which the second antennal article had two extra growths 
upon it.
