PSrCHE. 



[August--December 1SS9. 



Hab. Common, nearly everywhere. 

 I have seen the types of Burmeister, 

 Rambur, Selys and Say in Harris col- 

 lection. Canada, Quebec ; Maine, Nor- 

 way ; Massachusetts, everywhere ; New 

 York ; Wisconsin, Upper Wisconsin 

 River; Illinois; Ohio; Maryland; Ken- 

 tucky ; Kansas ; N. Carolina ; S. Caro- 

 lina ; Georgia; Washington, D. C. ; 

 Tennessee ; Florida ; Texas. 



The species described will perhaps 

 have to be reduced to four. The mate- 

 rial known for C. angtistipoDiis is de- 

 cidedly not adequate ; if a larger num- 

 ber should prove the differences given for 

 C ainata not persistent, the two spe- 



cies will belong together. I acknow- 

 ledge this to be possible ; after our 

 actual knowledge the union can not be 

 proposed on mere guessing. 



C. dimidiata and C. aplcalis have 

 to be accepted as belonging to the same 

 species. 



C aeqiiabilis has nothing to do 

 with C. dimidiata. C. tnac?ilata is 

 very striking, and surely different from 

 all the other species. 



C. splejideus Hagen Synops. Neur. 

 N. A. 5S.6 is surely not to be found 

 here. It was quoted after a specimen 

 in Escher Zollikofer's collection, said to 

 have been sent from Georgia bv Abbot. 



A CONTRIBUTION TOWARDS A KNOWLEDGE OF TERMITES.^ 



We will begin with Calotermes Jlav- 

 icoilis. I am able to state that individ- 

 uals (young nymphs) provided with 

 short wings, ^ wing pad of Hagen, can be 

 developed into supplementary kings and 

 queens. 



These supplementary kings and 

 queens are : 



I. Individuals (youngest larvae of 

 Fritz Mviller) which are not developed 

 enough to be considered either as sol- 

 diers (in Calotermes there are no 

 workers) or as sexually mature forms

- 1 use this term in the Fritz MUUer sense, for the 

 first formation of the wing, just as wing-stump (scale) 

 is used for what remains after the wing is torn off.

with fully developed wings (winged 

 individuals of Fritz Miiller.) 



2. Sexually mature larvae and 

 nymphs with longer or shorter wings. 

 I have some supplementary kings and 

 queens two and three years of age 

 which show the same characters that 

 they did at the time of their election, 

 and consequently they do not show the 

 slightest development of the wings, the 

 color of the body alone has become 

 darker (yellowish brown) . 



The sexual organs of the supple- 

 mentary kings and queens are identical 

 with those of the true kings and queens. 

 The anal appendages which are always 

 presei\t in tlie true queen are often
