Two pfedogenetic individixals had each laid an fc^o- whicli was adhering to 

 the side of the body. 



One liad transformed to tlie pupa of the a<lult $ . 



The cells of the pnpa and one of the oviparous pa^dogenetic individi\als 

 were less than 3 mm. apart, and in wood of the sam<^ character of decay, which 

 fact would appear opposed to the idea of food differences controlling develop- 

 ment, unless early in their history. 



Of the above, some were preserved, some died ; the young were placed in 

 new cells with pulverized wood to try to raise them. The pupa transformed to 

 an adult female which lived about five days and died unmated. One of the two 

 pcedogenetic individuals, with attached egg, rubbed the egg free, and the latter 

 was lost in the wood debris. Next day the other specimen had two adhering 

 bodies — one egg and one young Curculioid larva, the latter being in the posi- 

 tion on the mother in wliich her first egg had been. The new egg may have 

 been the one lost by the other reproductive individual, or may have been a 

 second egg laid by the one who carried it. At any rate, the first larva had the 

 advantage, and the next day the rival egg had disappeared (supposed to have 

 been eaten) ; the larva had its head in the vulva of the mother and was growing 

 rapidly, feeding on the contents of her body, but latei-, wlien full-fed, became a 

 victim of mould, and died." 



COLEOPTERA IN CAMBRIDGESHIEE AND HUNTINGDONSHIEE. 

 BY H. FORTESCUE FRYER, F.E.S. 



The following list of GoJeoptera taken in Cambridgeshire and 

 Huntingdonshire does not purport to be a complete County List, but 

 it may perhaps be of assistance to some worker who at a future time, 

 by an exhaustive- search through the records contained in various 

 publications, may compile such a catalogue. 



I am aware that a communication of this kind is lacking in 

 general interest, but it seemed inadvisable that the results of nearly 

 ten years systematic collecting should be lost : more especially as the 

 districts Chatteris and Holwoods, which are contiguous and occupy 

 an area of some 30 square miles, have been regularly and more or less 

 thoroughly worked, and, exchiding the Trichopterygidc'e, it is very 

 seldom that a fresh species comes under notice. 



The species enumerated are those I and my son, J. C. F. Fryer, 

 have taken during the years 1905 — 1913 ; in some few cases the 

 record of a species goes back to 1879 — 1882 ; when these records have 

 not been confirmed during the period first mentioned, the words "old 

 record " have been added. In cases where only one specimen of a
