LARVJE OF THE PEIOXIX^. \) 



The ventral mouth parts are large (PL II, fig. 4), fleshy, and more 

 strongly coriaceous than m other longicorns, attached by the sub- 

 mentum to the gula. The maxillary palpi are short, conical, and 

 robust, three-jointed, the joints often being wider than long; the last 

 joint is relatively short, either cylindric, blunt, or conical, the tip 

 being truncate and bearing a sensitive impression; the ligula is large, 

 fleshy, and very densely covered with short, stiff hairs. 



The gula (PL I) is short, its lateral sutures diverging behind 

 to meet the large fovea, in which are attached the inferior retractor 

 muscles of the head. Beside the gula on each side lies the large 

 hypostoma, with its external sutures convex and meeting the attach- 

 ments of the tentorial bridge; this last is a trapezoidal transverse 

 plate separating the occipital foramen into an anterior and a posterior 

 portion. (PL I, Orthosoma.) 



Laterally between the articulations of the mandibles is the heavily 

 chitinous region, the pleurostoma, on which the ocelli are situated. 

 Behind the ventral articulation of the mandibles is a prominent 

 tubercle or process, for which I propose the name, subfossal process. 

 Behind the dorsal mandibular articulation on the front is a more or 

 less prominent carina, for which I propose the name, postcondylar 

 carina. 



The antennae are placed at the extremity of the frontal sutures, 

 between the pleurostoma and the distal angle of the front. They are 

 two or three jointed with a jointlike membranous base, conical, 

 retractile, and protected by a projecting chitinous shield from the 

 front, above the antennal ring. The last joint is barrel-shaped or 

 cylindric, obhquely truncate, hoUowed at the tip, and bears in sev- 

 eral genera a smaU. third joint in this fovea. In Parandra this third 

 joint is quite long. 



In harmony with other structures the mandibles are strong and 

 robust, triangular from the outer side, with that face more or less 

 strongly rugose. The apex is extended and acute, the cutting edge 

 obhquely emarginate, the molar portion either rounded, produced 

 in a blunt tooth, or flattened into a striated plate. 



The body, as in all Cerambycidae, consists of three thoracic and 

 ten abdominal segments, the tenth being the anal lobes. 



Of the thoracic segments (PL II, fig. 5) the first is the largest, nearly 

 equal in size to the second and third. It is always more strongly 

 chitinized than any other body segment and bears scattered coarse 

 hairs. The prothoracic segment differs considerably from the meso- 

 thoracic and metathoracic segments. The pronotum is median, 

 nearly square, the posterior half limited at each side by a longitudi- 

 nal suture; it is smooth anteriorly, rugose to a varymg degree 

 posteriorly. The mesonotum and metanotum are very short and 

 each is divided by two diagonal sutures which intersect medially. Just
