Longicoriiia Malaymia. 461 



Between tlie extremes of this large genus the variations from 

 the type, except in colour, are not very remarkable. In 

 many species a large centro-basal spot is found, and as this 

 is generally glabrous and occurs in the most convex or exposed 

 part of the elytra, it might be thought to be due to abrasion ; I 

 l)elieve, however, that this is not the case, as it is far too general 

 and occurs in the freshest examples. The greater part of the 

 species are spotted or banded with white or grey, one species 

 only is striped^ — 7'. phaleratus ; these colours are principally due 

 to a very dense pubescence hiding the derm beneath, the intervals 

 having a finer and sparser pubescence, through which the derm 

 appears. There is very little difference between the males and 

 females. They are generally found in the gloomy dark forests, 

 gnawing bark or twigs of trees, and have a peculiar drone when 

 flying ; they are, however, sluggish animals, dropping down when 

 touched, with their legs and antennae drawn close in to their 

 bodies. The descriptions here given will not always be found in 

 exact accordance with other authors, especially those of MM. 

 Blanchard and Boisduval, but in most cases my specimens have 

 been compared with such of their types as are in the Collection 

 of the Jardin des Plantes.

Head and prothorax dark brassy, with a sparse fulvous pu- 

 bescence, varied with fulvous spots, and with few coarse punctures; 

 scutellum rounded at the sides and apex, margined with fulvous ; 

 elytra dark greenish-brassy, very glossy, with a very few coarse 

 punctures only at the base, four or five reticulated bands (the 

 apical mostly forming two) composed of numerous more or less 

 connected fulvous spots ; body beneath spotted with fulvous at 

 the sides; legs brassy, thickly pubescent, the tarsi greyish j 

 antennae covered with a short fulvous pile.
