AbstractLately I have had the pleasure to receive an interesting collection of Brenthidae from West Java, very kindly offered to me by Mr. J. D. Pasteur to whom I here wish to express my sincere thanks.
In the letter accompanying this valuable lot of specimens, Mr. Pasteur gives some remarks on the coloured lines and spots of the elytra in living Brenthidae and says: »Les taches jaunes sont toujours d’un jaune très clair (jaune de paille ou bien de gomme gutte) faisant un vif contraste avec la couleur laque noire des élytres; aussitôt que l’insecte est desséché ces taches jaunes deviennent d’une couleur fade, brune claire ou même foncée.” In my note: Enumeration of the species known as yet from Java 1), treating of Eutrachelus Temmincki Latr., I wrote: »this species varies in having the elytral spots more or less evident”, but Mr. Pasteur notices: »Les E. Temmincki Latr. que j’ai collectionnés par vingtaines de toutes dimensions et des deux sexes à Sumatra aussi bien qu’à Java, avaient toujours les taches d’une couleur jaune très claire de gomme gutte.” And indeed, in a few specimens belonging not only to the genus Eutrachelus but also to Miolispa, Baryrrhynchus, Orychodes, . Pseudorychodes etc. that Mr. Pasteur sent to me preserved in arsenical glycerine, the colour of the elytral lines and spots is very bright and strongly contrasting with the dark general tint. In dry specimens preserved in the collections, the differences of colour of the elytral markings are probably due to the different manners of conservation, but I believe also that some species are less subject to this darkening.
