Larva short, thickened, wrinkled and curled in burrow when at 

 rest; head chestnut brown, lightest in center where it is bisected by 

 two darker lines, arcuate on hind margin; jaws black, antennae and 

 palpi reddish brown. 



Pupa Pale yellow with black eyes; tip of snout and spines on ab- 

 domen reddish brown, wing-pads dark colored at tips; dorsal surface 

 of head smooth, bearing a few scattered hairs; thorax broad showing 

 a depression on either side and a central suture; abdomen tapering to 

 extremity, each segment furnished with a spine on either side with 

 anal one bearing two and a number of spiny hairs at apex; surface 

 shows several fine hairs upon head with two longer ones above eyes; 

 snout and legs curled downward, wings folded down forming a pad 

 on either side. 



This insect was evidently introduced into New Jersey green- 

 houses in orchids imported from some tropical country of the 

 Eastern hemisphere and while it is not by any means common, 

 it is not unusual to collect a specimen or two by diligently 

 hunting through a house of Dendrobiums. During the middle 

 of the day the beetles seem to prefer to rest in the curled, 

 basal portion of the leaf, where a considerable part of their 

 feeding takes place. In New Jersey, Dcndrob'mm findlayanum 

 and D. crystallinum seem to be attacked more than other spe- 

 cies as I have found entire specimens of these plants com- 

 pletely riddled by the larvae. 



Diorymellus laevimargo Champ. (Col.). (Plate V, fig. 4.) 



This little, black, shiny fellow, which is only 2 mm. long and 

 i mm. wide and also a member of the Barldae, is sometimes 

 excessively abundant in orchid houses feeding on Cattleyas 

 and Dendrobiums. Cattlcya mossiae and C. speciosissinm 

 have been the ones particularly subject to attack. In addition 

 to feeding on the leaves, pseudo-bulbs and flower stalks, 

 the orchid-growers credit this beetle with doing considerable 

 damage to the flowers and unopened flower buds. Plate IV, 

 figure 2 shows the somewhat hard discolorations and spots, 

 usually at the tips and edges of the petals and sepals, which 

 surround the feeding punctures. I have been informed that a 

 somewhat similar-looking injury follows improper ventilation 

 and watering. Such markings of course make the flowers un- 

 salable or reduce their value. The beetles can be found, some-
