fcnse, aggression, and tilillation on the part of the male prepara- 

 tory to copulation. One S. American species (Sphiiigolabis 

 linearis) is stated to cause much annoyance and painful wounds 

 with its forceps, "leaving double puncture marks on the skin." 



But few parasites have been observed or recorded ; Lucas ob- 

 tained a yellow parasitic worm, which he suggests is a Nemathel- 

 n}inthid iMcnnis sp.), from a specimen of Forlicula auricularia, the 

 abdomen of which was much swollen. Two Tachinids are re- 

 corded ; Rodzianko stating that Roesclia aiitiqiia was bred from 

 an East European species, Forficula tomis, and Fischer records 

 another ^y, Tachina sctipcnnis from Forficula sp. 



Of the eight species known to be established on these islands, 

 the five following have been observed in the cane fields : 



1. Aitisolabis ainiulipcs, Lucas. Common generally. 



2. Labia pygidiata, Dube. Common locally. 



3. Labia sp. Not common. 



4. Labidnra sp. Not common. 



5. ChclisocJics iiiorio, Fab. Common in the wet districts. 



Of these Chclisochcs morio and Auisolabis anmdipcs are of con- 

 siderable economic inportance and have therefore been parti- 

 cularly studied. 



CFIELISOCFIES MORIO. 



(t) General Remarks. 



Of the species in these islands, this fine Forficulid is certainly 

 the most important economically. It has a wide distribution 

 in the islands of the Pacific Ocean, and is recorded from Tahiti, 

 Fiji, Llawaii, New Guinea, Java, Sumatra, Celebes, PhiUppines. 

 Batchian, India and Ceylon. 



It is an extremely active species, especially during the larval 

 period, and appears to be diurnal, running over the leaves in 

 search of insect food during the hottest part of the day. The 

 adults will readily take to flight, the unfolding of the wings be- 

 ing a very rapid process and quite independent of the forceps, 

 the writer never having seen them used either to assist in the 

 folding or unfolding process. Wet localities seem to suit it best, 

 since it abounds in the moist mountain ridges and valleys, and
