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

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

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

 on segments 5-11 and 13. Cimbicidae have (22) prolegs on 5-11 

 and 13. 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 Cimbicidoe. Lophyridae have (22) 

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

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

 abortive prolegs on segments 6-n 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, 

 besides 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. 



Hcematobia 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- 

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

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

 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 

 .(Corresp. Blatt. Regensb. 18, 164, 1864). HENRY SKINNER.
