OF CURCULIONin.E INJURIOUS TO CYCADEiE, ETC. 129 



trouver des plantes saines dans la variété. L'insecte parfait se trouve 

 le jour dans la partie végétante formant le cœur de la plante. — 

 Quant aux dégâts, ce sont identiquement les mêmes que ceux du 

 Pliaczcorymis funerarins Murr. » — In the accompany figures I 

 hâve represented various portionsof the stem of the Zamia corallipes 

 shewing the injurions ravages of the larva with the cylindrical 

 burrows in which thej réside. 



The larva of Tranes internattis is of a creamy white colour with 

 the head chesnut brown, the mandibles and lower part of the 

 mouth brownish black. The segment of the bodj following the head 

 has on the upper side two broad clear-brown plaques of a horny 

 consistence. This larva is of a much more cylindrical form than that 

 of the larvœ of the Phacecorymcs, the body generally somewhat 

 arched; it is destitute of legs the underside of the firstthree segments 

 with two or three short bristles which are also shewn in Bur- 

 meisters' figure of the larva of his Cal. Sommeri. — The mandibles 

 are very strong, triangular and acute at the tip, below which is a 

 notch forming a small sharp tooth; the maxillse are broad, flattened 

 and rounded at the tip where they are armed with short obtuse 

 spines; the maxillary palpi are very short and two-jointed.They are 

 connected with the lower tip by a broad membrane. The mentum 

 is small obtriangular with the middle of the fore margin produced 

 in front, pointed behind, the anterior angles form two broad joint, 

 like pièces; the labial palpi are very short and two jointed. — The 

 spiracles are nine pairs in number, the first being the largest and 

 placed on the segment next the head; the second and third 

 segments are destitute of spiracles, and the fourth and seven fol- 

 lowing segments hâve one on each side of the body. 



The body is much wrinkled and the terminal segment is entire 

 without any tubercle or projecting appendages. 



The perfect insect varies from 10 to 12 millimètres in length, 

 exclusive of the rostrum which is about the length of the pronotum. 

 The antennas are 9-jointed, the long basai joint being lodged, when 

 at rest in two grooves extending on the underside of the rostrum 

 quite to its base as shewn in my figure.
