SUMMARY OF OUERENT RESEARCHES RELATING TO 



individuals. Those which become mature in spring get completely 

 developed wings and then leave the maternal nest to become the true 

 kings and queens of new colonies ; this, however, very rarely happens to 

 them. Those which become mature in summer copulate and multiply 

 (complementary kings and queens). The complementary kings die 

 before the beginning of winter, so that the queens alone survive ; these 

 cease to deposit eggs in winter and spring, but begin again in May ; 

 they then make use of the sperm which they have kept stored up in their 

 spermatheca since the preceding autumn. The author does not know 

 how long the complementary queens may live, but it is probable that 

 they die when the next set of complementary kings and queens becomes 

 mature. The various forms of Termites are exhibited in the accompany- 

 ing table : —

Abdominal Appendages of a Lepismid.* — Dr. J. T. Oudemans 

 gives an account of the abdominal appendages of the little known 

 Thermophila furnorum. They are found on the seventh, eighth, and 

 ninth ventral shields, but do not all appear until the creatures are 

 adult ; they appear in order from behind forwards. These processes are 

 not rudimentary organs and therefore have nothing to do with the 

 primitive legs. They are found in males as well as in females, but 

 seem to appear in the latter somewhat earlier than in the former. 



Galls produced on Typhlocyba rosse by a Hymenopterous Larva.f 



— M. A. Giard calls attention to the death last October of a large 

 number of specimens of Typlilocyha rosse ; further investigation has 

 shown that they become the prey of a hymenopterous larva which has a 

 close resemblance to that of Misocampus.
