. Coleoptera : general introduction and Cicindelidae and Paussidae. ge 275 I have said that I cannot find that anything isknown of the life-history of Tricondyla and Derocrania. Just asthis book is going to press the last volume of the ZoologicalRecord has been published, and 1 find that I have missed a paperby Dr. van Leeuwen in the Tijdschrift voor Entomologie, June1910, pp. 18-40, plates 2 & 3, entitled Ueber die Lebensweiseund die Entwicklung einiger holzbohrenden Cicindeliden-Larven,and containing the life-histories of Collyris bonelli and tubercidataand of Tricondyla cyanea. We have no space to enter into thedetails of this paper, further than to state the remarkable similarityof the Tricondyla larva to that of Collyris : the fifth abdominalsegment is humped in the same way and has the three smallhooks on each side, and the insect has the same habit of makingburrows in the stems of the coffee-shrub and seizing its prey atthe entrance of these. It is, of course, larger, being 20 length, but otherwise there is very little LIFE-HISTORY OF TRICONDYLA AND COLLYRIS. 51 5 Mr. H. E. Andrewes has kindly sent me a letter, received fromMr. H. Leslie Andrewes, which throws further interesting lighton the life-history of Collyru • he writes as follows:—I waspruning some 4-year old tea, and, when cutting through a branchabout two years old, I went through the fore portion of theabdomen of a Collyris sp. ? (imago), and the front part wriggledout of the hole and dropped on the ground. The branch wasabout five-eighths of an inch thick. There was an external hole(presumably for getting rid of excrement) at an angle of about120° witb the burrow in which the beetle was. It w as stoppedup with blackish excrement. There was a very little powderedstuff in one end of the hole which had evidently been apupal envelope of some kind, presumably that of the Andrewes does not think that the beetle could possibly havegot into the branch for predatory
