in Europe, either native or in liothouses. The figure represents the 

 new species in a sac on a twig of artemisia. 



Biology of the cockchafer (Rev. ScL, ser. 4, 7 {1897)^ No. 1, pp. 

 27^ 28). — Some observations on the life history of Melolontha vulgaris. 

 Older authors are criticised and the eggs, larva, nymph, and imago 

 described anew. The main point made is that the adult insect lives 

 from 45 to 62 days, much longer than nas previously been described. 

 A few observations are also made on the destruction of white grubs. 



Insects injurious to stored grain and cereal products, A. L. 

 QuAiNTANCE {Florida Sta. Bui. 30, pp. 358-3S5, fiffs. 10). — In this are 

 given mostly compiled short popular accounts and descriptions of the 

 Angoumois grain moth {Gclechia cerealeUa), the meal snout moth {Py- 

 ralis farinalis), the Mediterranean flour moth {Ephestia l-Hehniella), the 

 Indian meal moth [Flodia interpunctella), the granary weevil [Calandra 

 granaria), the rice weevil {C. oryza), the bean weevil {Bruchus ohtectus), 

 the Chinese cowpea weevil {B. chinensis), the four spotted bean weevil 

 {B. quadrimaculatus)^ the pea weevil {B. pisi), the slender horned flour 

 beetle {Bchocerus maxillosus), the confused flour beetle {Triboliiim con- 

 fusum), the rust red flour beetle {T. ferruginemn), the red grain beetle 

 {Carthartus geniellatns), the corn silvanus {Silvanus surinamensis), the 

 grain eating brachytarsus {Brachyfarsus alternatus), and the catorama 

 flour beetle {Catorama punctulata). 



Of these the rust red flour beetle and the corn silvanus, besides their 

 usual destructiveness to cereals, etc., are mentioned as serious museum 

 pests. The confused flour beetle is said not to be present in great 

 numbers, but may become so, while the meal snout moth and the Med- 

 iterranean flour moth, which are at present not known to occur in 

 Florida at all, may be expected at any time. 



The grain eating brachytarsus is reported for the first time as injuri- 

 ous to stored grain ; the larvte have previously been supposed to be 

 l^arasitic on scale insects and coccids. But it has been found feeding 

 in larval and adult condition in stored cowpeas and English peas, and 

 doing serious damage. 



The most injurious of this list are the Angoumois grain moth and the 

 rice weevil. 



Fully 20 per cent of all corn stored in granaries, the author esti- 

 mates, is destroyed hy insects, which signifies an annual loss to the 

 State of $492,598.15. 



As a remedy the use of carbon bisulphid is recommended. 



Some Mexican and Japanese injurious insects liable to be 

 introduced into the United States ( U. >S. IJept. Agr., Division of 

 Entomology Bui. 4, tech. ser., pp. 50, Jigs. 0). — This bulletin consists of a 

 series of articles, 3 of which relate to Mexican insects, 1 specifically to 

 Japanese insects, and 2 to insects which may enter this country mainly 

 from Japan, but also from other Pacific ports, principally Hawaii and 

 Australasia.
