 Figures caterpillar mouth-parts and legs.

 logique de France, vii, 385, Paris, 1887. 



He has a pretty series of figures of the true legs as well as the 

 prolegs, but unfortunately it is a very superficial study.

Refers more especially to the presence of a complete circle of 

 crotchets in the lower forms. 

 Setae. 



Dyar, Harrison G., A Classification of Lepidopterous Larvae. Annals of 



the New York Academy of Science, viii, 194 to 232, New York, 1895. 



Although he has led up to it in a couple of descriptions in 



Entomologica Americana, this paper of Dyar's is really the pioneer 



work on caterpillar setae as a means of classification. A large 



number of caterpillars are discussed from this point of view.
