parent characters takes place, while in other cases (Japanese " whites " 

 X Siamese " yellows " or " Japanese " whites " x European " yellows ") 

 it may often be observed. Sometimes it happens that both dominant 

 and recessive characters, even sexual ones, appear as active characters in 

 an individual body. 



Coleoptera and Moths of United States.* — C. Schaeffer gives some 

 notes on new genera and species of Coleoptera found within the United 

 States. Short descriptions of the Mexican species are given. There is 

 also recorded a list of Bombycine moths from the Huachuca Mountains, 

 Arizona. H. G-. Dyar describes several new species of moths, also from 

 Arizona. 



Bionomics of South African Lamellicorns.f — G. B. Longstaff 

 gives some interesting notes on certain species of Cetoniinae and 

 Hopliinse. These beetles apparently play a large part in the fertilisation 

 of flowers, and amongst the examples referred to are some protectively 

 coloured like the plants they visit, cases of mimicry, e.g., Gametis balteata 

 resembles certain Lycoid beetles which are very distasteful to Kestrels 

 and Baboons. An interesting case is that of Heterochelus $ , which 

 has greatly elongate and denticulate hind legs. These project above 

 the florets when the beetle is busy burrowing into the disks of Com- 

 posite with its body almost completely buried. They resemble the 

 widely separated jaws of an ant-lion, and on being touched can give a 

 very respectable pinch, inflicted by the formidable teeth upon the inner 

 margins. These legs were probably in the first instance adapted to 

 assist the male insect in grasping its mate. 



Abdomen of Female Chafer.}— B. Wandolleck gives a comparative 

 account of the morphology of the abdomen of the female in sixteen 

 species of Cerambicidee. Although there appear to be three types, these 

 are connected by intermediate forms, so that a fundamental similarity 

 exists in all. 



Stegomyia fasciata and Yellow Fever.§ — E. Marchoux and P. L. 

 Simond find that there is a possible hereditary transmission of the 

 amaril virus in Stegomyia fasciata. An infected mosquito may produce 

 eggs which give rise to infected individuals. But this does not play an 

 important role in the propagation of yellow fever. The mosquito is not 

 infected either by blood from haemorrhage, or by vomit, or by fgeces ; 

 larvae reared in water with dead bodies of infected mosquitos are not 

 infected. The virus may be artificially passed from mosquito to 

 mosquito, but this does not occur in nature. The adult insects kept in 

 contact with the dead bodies of infected forms are not infected. Unlike 

 many other Culicidae, the female Stegomyia fasciata does not die after its 

 first oviposition. 



New Sense-Organ on Head of Corethra Larvae. || — Em. Radl 

 describes a peculiar sensory organ on the head of this larva. It has
