SÉANCE DU 7 AOUT 1886 



In the autumn of lastyear I received frora Monsieur J. Ch. Puis 

 of Ghent a verj interesting communication concerning certain 

 Coleopterous insects which he had found to be injurious to species 

 of Zamise cultivated in the serres of that city. For several years 

 previously he had found the Phacecoryniis Zamix of Gyllenhal 

 (Schon., p. 963), attacking the Cycadeae, but at the date of his com- 

 munication (7. August 1885) he wrote to me : « Aujourd'hui je 

 trouve un autre insecte qui détruit l'intérieur des Cycadées, celui 

 qui est ci-joint a été trouvé dans le Zamia villosa dont les larves 

 ont entièrement détruit la plante et font de grands dégâts dans la 

 serre. Vous m'obligeriez en me faisant connaître si le nom est exact 

 et quel est le nom de l'autre espèce. » Subsequently M. Puis was 

 so obliging as to send me a plant of the Zamia attacked by the 

 insects with spécimens of both the latter species together with the 

 of his second species. 



The first mentioned insect was correctly named by M. Puis as the 

 Pliacecorynus Zamiœ, a Weevil belonging to the gronp of Calan- 

 drides, of an obscure black colour more or less varied with red 

 spots on the elytra or with the elytra obscurely ferrnginous covered 

 with minute black dots; in the middle of the pronotum or dorsum 

 of the prothorax is a small velvety black oval spot and another 

 small and posterior is just in front of the scutellum; this may 

 possibly be a sextial character as there are some spécimens in which 

 they are wanting, where, however, they may possible hâve been 

 rubbed ofF. In ail the individuals of PJiacecorynus Zamix sent to me
