xv, 3 Banks: Two Philippine Buprestids 291 



The prothorax has the laterocephalic lobes strongly, roundly 

 produced cephalad, their anterior margins being on a line with 

 the tip of the mouth or a little beyond. Its integument is finely 

 reticulate-punctate and its lateral and cephalic margins are 

 sparsely white haired, especially the lobes. 



The mesothorax is two-thirds the length of the prothorax 

 and is minutely punctate, these two segments being consequently 

 dull glabrous. All the segments of the body caudad of the pro- 

 thorax are strongly lobed laterad, except the twelfth, thirteenth, 

 and fourteenth, the last being spherical; the other two, evenly 

 rounded laterad; and the penultimate, five-eighths as wide as 

 the antepenultimate. 



The caudal margins of the first to the sixth abdominal seg- 

 ments are one-third to one-half longer than the cephalic mar- 

 gins; hence the lateral lobes are obcordate in outline (Plate 

 II, fig. 3) and the segmental incisions are very deep. At the 

 base of each lateral lobe on the dorsum is a convex, lunate, 

 longitudinal sulcus which, with its neighbors, roughly outlines 

 the lateral limit of the abdominal segmental articulations. 



On the ventrum the second to the eighth abdominal segments 

 are provided with sublateral, circular pseudopodal papilla 3 , 

 laterad of which appear sulci, as dorsad, but somewhat more 

 profound (Plate II, fig. 4). 



In the last instar and previous to cessation of feeding, the 

 larva measures 10 millimeters in length and is more buff or 

 very dark cream, darker on the thoracic segments. The scu- 

 tum and sternum of the prothorax are sharply outlined and 

 darker and more chitinized than the surrounding integument. 

 The anal segment is obtusely bilobed caudad. The abdominal 

 pseudopodal papilla? are more prominent and glabrously cor- 

 rugated. 



The movements of the larva are very sluggish, both in the 

 mine and when removed therefrom, and it has the peculiar 

 habit of switching its tail from side to side in the gallery, thus 

 leaving behind a fine string of excreta in a broad zigzag chain 

 (Plate I, figs. 1, 2, and 3). 



PUPA 



The pupa just after formation is 6 millimeters long and 2.25 

 millimeters wide, and is greenish cream-white, glabrous, and 

 subcutaneously opaque. It follows very closely the general 

 form of the adult except that its abdomen is narrower, with 

 the segmental articulations constricted somewhat as in the
