that the larva upon emergence from the egg has "six or eight" 

 antennal segments, this number being increased by two at each 

 moult, and that the adult possesses fourteen segments. As 

 regards the number of moults, he is also uncertain, stating that 

 there are "three or four." Now, although possible, it is improb- 

 able that the number of ecdyses should normally vary in these 

 two types. We know that the number of moults in Chelisoches 

 is four, and that the increase of the antennal segments at each 

 successive moult is as follows: four (1st moult), four (2d moult), 

 three (3d moult), one (4th moult). Assuming that there are 

 four ecdyses in Forficula, and that the somewhat fragmentary 

 data of Meinert are correct, we obtain the following comparison: 



Whether the above problematic increase is correct for 

 Forficula auricularia requires to be verified, and it will be of 

 interest if some entomologist having access to this common 

 species will investigate this question. 



Mr. J. KoTiNSKY read notes on a " Hymenopterous Parasite 

 of an Orthopterous Egg," and exhibited specimens. 



Last October I collected up Nuuanu Valley a leaf which con- 

 tained an Orthopterous egg from which in November issued 

 Anastatus koebelei Ashmead, as determined by Mr. Perkins. 

 This month I received a collection of eggs that seem to be a 

 similar, if not the same, species, from Hilo, Hawaii, on coffee 

 leaves, collected by Bro. Matthias Newell. From these I bred 

 a large number of a small black Chalcidoid parasite, which, 

 judging from its size, seems to be secondary. 



The host has since been partially reared and found to be 

 Elimaea appendiculata, which Mr. Perkins states, habitually 

 oviposits in young shoots of trees hke the Avocado Pear.
