194 THE ENTOMOI>OGIST's RECORD. 



plant's power from the summary of species in which 42 Heuiiptera, 

 58 Coleoptera, 165 Hymenoptera and 117 Diptera, a total of 382 

 species are recorded. In addition to this a number of species were not 

 identified and a few Lepidoptera have been omitted. Truly a formid- 

 able number when one is told that the flowering period lasts but three 

 weeks at the utmost. 



In the I'hit. Neils for April is a very interestinp; account of the 

 hybernating habit of Cicuvli'la sieinliR in California. Little piles of 

 earth were noticed around the edges of large pieces of rock lying on 

 the ground. One of these rocks was raised and numerous burrows 

 were found, each containing a beetle at its inner extremity and blocked 

 at its mouth by the removed earth. Under three such rocks as many 

 as 64 specimens in all were obtained. 



In the Knt. Mo. Mar/, for March, Mr. E. A. Butler adds a new 

 species of Hemiptera to the British List in the Capsid, Psallna ritellinus, 

 of which six specimens were taken in a plantation at Colesbourne in 

 July, 1911. 



In the same number Mr. James Edwards records another addition 

 to the British List, viz., the Hemipteron, Psi/lUi alhipes, taken by Mr. 

 W. West, at Box Hill. 



The Hon. N. C. Rothschild, in the same number, recorded a new 

 British Flea, Pahienpsi/lla kolianti, of which three specimens were 

 taken from a mole captured in March, 1911, at Ballindalloch. 



In the April number of the Knt. Mo. Maij. Mr. A. E. J. Carter 

 announces a Dipteron new to Britain, ri::., Triotnna trisiilrota, taken 

 in 1899 at Sutton Coldfield and only recently rightly identified. 



Mr. Porrit, I'/nt. Mo. Ma;/, for April, names the very distinct local 

 form of IJybrrnio anrcnitiaria from S.W. Yorkshire, as vsiv. fin^ca. It 

 is of a uniform fuscous-brown without trace of the usual markings, 

 and has occurred regularly for some years past. 



In the May number of the Fnt. Mn. Maij., Commander J. J. 

 Walker announces Claviijer loiKjicortih as a Coleopteron new to Britain, 

 taken in the Oxford district. 



Mr. J. E. Collins describes, in the Knt. Mo. Ma;/, for May, three 

 species of the Dipterous genus IJetcroiicnra as new to science and to 

 Britain, tiz., H. calcdonica, from Nethy Bridge, H. iientili^, from 

 Lyndhnrst, etc., and H. rerticalis, from Dolgelly, Nairn, Studland and 

 Bridgend. 



In the May number of the Knt. Mo. Mcuj. Mr. Norman H. Joy 

 describes a new form of the Coleopteron Microiiloasa i»ar;iinalis as var. 

 ob.<iciira. It was obtained at Strathfieldsaye, Hants, in 1909. 



To those interested in '"Alternation of Generations" we would 

 suggest a glance at the diagram given in the May number of the Knt. 

 Neus, illustrating the life-cycle of the malaria parasite. The infection 

 takes place through the biting of the human victim and the injection 

 of the " sporozoite" with the salivary secretion of the mosquito. In 

 the human blood this " sporozoite " develops into an active amoeboid 

 " schizont " which enters and feeds upon the blood corpuscles. These 

 parasites multiply asexually and intensify the attack and its results on 

 the human victim. Some of the parasites are subsequently sucked up 

 by other mosquitoes while biting the malarial patient, and undergo their 

 sexual generation in the blood of the insect, producing in turn fresh 

 " sporozoites " which infect other victims.
