brown as far as the little antennae, the remainder yellowish white ; the 

 margin of the clypeiis and the lower part of the frontal suture were also 

 of this colour. The bead was rough anteriorly, and, for so far as the 

 brown colouring extended, thinly covered with pale brown hairs. The 

 eyes were sealed in round black spots ; the upper jaws were yellow at 

 the base, pale brown further on. 



A short time after this I found no more larvae on the rose-leaves, 

 nor could 1 perceive any pupae : I thus came to the conclusion that 

 the larvae had descended from the leaves and gone into the earth, for 

 the purpose of passing through the pupa state in that situation. 

 I had placed in a glass some rose-twigs having curled-up leaves; at 

 the bottom of the glass 1 had put a layer of earth, and in this 1 found 

 some cocoons : ihey were very strongly made, being spun inside, and 

 consisting of grains of sand on the exterior ; I have figured one at fig. 5. 

 I subsequently, however, failed to find any images in the glass in 

 question, getting nothing but parasites. 



It will now be objected that this life-history is incomplete, and I am 

 ready to acknowledge that much is wanting. I have no certain proof 

 that the larva above described is the larva of this insect: there is 

 always the possibility that the larva of Selandria pusilla is totally 

 different in habits and appearance : true, but I have found the proba- 

 bility of identity so great that I cannot but regard it as ahnost 

 amounting in value to direct proof. Not a single one, but a hundred 

 and more imagos of the same species make incisions in the rose-leaves, 

 which, in consequence, curl up ; in the curled-up portion are found 

 not one, but more than a hundred larvae, all resembling each other; 

 must we not conclude that the larvae so produced are the brood of the 

 imagos in question ? 



The imago (fig. 6) is shining black. Head broad, with very dark 

 brown eyes ; antennae black, but little longer than head and thorax 

 together; palpi obscure yellow. The back and sides of the thorax are 

 smooth shining black, as is also the abdomen, the ventral surface only 

 having some silky pubescence. The wings are blackish, as if smoked, 

 the posterior pair being somewhat paler. The costal ncrvure and the 

 stigma are broad and black ; the course of the nervures, as is sometimes 

 the case with the smaller species of Selandria, is rather inconstant. 

 All the coxae are black ; the anterior femora black half-way, obscure 

 yellow further on (fig. 8) ; the intermediate femora are two-thirds black, 

 and obscure yellow for the remaining third ; those of the posterior 

 pair are black, having the knees obscure yellow. The remaining 

 parts of the legs of the first and second pairs are obscure yellow ;
