ii, pt. 2), by having only one ocellus and, when prolegs are pres- 

 ent, by there being more than ten and without hooklets. Patn- 

 philius has no prolegs. Tenthredinidse have (22 in all) prolegs 

 •on segments 5-1 1 and 13. Cimbicidae have (22) prolegs on 5-1 1 

 and i.v St. Fargeau's statement, quoted on page 9, of Norton's 

 "Catalogue," that the larvae of Zarcea and Abia have only 20 

 legs is erroneous ; for, I find Abia inflata Nort. to have 22 legs 

 in agreement with the other Cimbicidae. Lophyridae have (22) 

 prolegs on segments 6-13. Nematidse have (20) prolegs on seg- 

 ments 5-10 ( Cladius) or 6-1 1 and 13. Acorduleceridae have (20) 

 abortive prolegs on segments 6-1 1 and 13. Many apodous larvae 

 of Hymenoptera have an anal sucker. 



Phryganeid larvae have a pair of anal prolegs. 



Chrysopa has an anal disc used in locomotion. 



Panorpa larvae have 22 conical legs, situated as in the sawflies, 

 l^esides anal legs or processes. Bittacus has two-jointed legs on 

 •each of the nine abdominal segments. Sisyra has jointed appen- 

 dages on the first and seventh segments. 



Hcsmatobia larva has transverse rows of minute fleshy filaments 

 at base of six ventral segments. 



Simulium has a proleg on prothorax of larva. Chironomus 

 larvae have pairs of prolegs on the prothorax and on the last seg- 

 ment. The abdominal tubercles of Chironomus and Ephydra 

 bear hooks. Syrphus larvae have seven pairs of abdominal pro- 

 legs. Blepharocera larvae has six pairs of conical prolegs and six 

 median sucking discs ; the pupae has three pairs of suckers 

 beneath abdomen. 



In Coleoptera prolegs occur, ventral in Entomoscelis (Fletcher), 

 ventral and dorsal in Asclera and Nacerdes, dorsal in Mordellis- 

 iena, Cerambicidae, etc. (Riley). Anal prolegs (sucking discs) 

 occur in Lampyridae, Coccinellidae, Chrysomelidae, etc. Pky- 

 ■tonomus has tubercles without claws on all the ventral segments 

 and uses them in clasping the leaf; it has also an anal sucker 

 which it uses in locomotion. 



Mrs. A. T. Slosson has lately sent me a pretty and interesting species 

 of Thecla which she took in January of this year at Biscayne Bay, Florida 

 I saw at once it was new to our fauna, but is not new to science, as it was 

 described from Cuba by Herrich-SchafFer under the name of martialis
