of G. fulro-maeulata ; and this again is probably only a variety of 

 G. arouensis. It is a misfortune that these and many other equally 

 important questions can only be solved by naturalists on the spot ; 

 but in the meantime we must make the best of what is before us. 



Tanylecta. 



Antennae basi approximate. 



Pedes graciles ; femora linearia ; tibice intermedia emarginata. 



Ungues simplices in utroque sexu. 



Head nearly quadrate in front, the antennary tubers obsolete. 

 Eyes large, the upper lobe narrow. Antennas shorter than the body, 

 approximate at the base, the scape subcylindrical, slightly shorter 

 than the third joint, which is the longest, the rest gradually shorter, 

 all nearly cylindrical, the last a little thickened. Palpi slender. 

 Prothorax oblong, scarcely broader than the head, regular above, 

 the sides towards the base vertically impressed. Elytra elongate 

 cuneate, broadest at the base, the shoulders prominent, the sides 

 abruptly declivous, the angle forming a carina, the apex of each 

 acuminate externally. Legs slender, unequal, femora linear, inter- 

 mediate tibiae emarginate ; tarsi with the basal joint elongate ; claws 

 simple in both sexes. Anterior acetabula slightly angulated. Pro- 

 and mesosterna rounded. 



The approximate antennae and simple claws might seem to sepa- 

 rate this genus from the Phytceciina ; but, on the other hand, its 

 location at any distance from Glenea would be most unnatural. The 

 female is much stouter than the male, but there is no other difference. 

 The upper surface has deeply impressed punctures, much coarser on 

 the elytra, on which a second carina is found at the side, commencing 

 a little distance from the shoulder, but both terminating at the apex. 



Tanylecta lambii. (PL XXVIII. fig. 9.) 



T. nigra, nitida, lineis maculisque albo pubescentibus ornata ; 

 antennis albis, nigro annularis. 



Black, nearly glabrous, shining, with lines and spots composed of 

 short white hairs ; head with two central white lines and a line be- 

 hind each eye, which are continued on the prothorax, the central, 

 however, almost or quite contiguous, and the lateral having a sup- 

 plemental line below it ; scutellum scutiform, white ; elytra covered 

 with small round white spots, the suture bordered with white ; body 

 beneath black, with a broad white stripe from the cheeks to the end 

 of the abdomen, the sternal and abdominal portions of the stripe 

 with glabrous black patches ; legs and centre of the abdomen with 

 a delicate greyish pile ; antennae not so long as the body, white, the 

 joints from the fourth to the tenth, the eleventh entirely, black. 

 Length 10 lines. 



Zosne. 



Antennae basi distantes ; articuli ultimi sex abbreviati. 

 Pedes mediocres ; tibice intermedia integra. 

 Ungues basi obtuse dentati.
