is not known, and it is therefore probable that this larva belongs to the 
genus, as probably also does the following one. 
Larva B 
Body black, legs reddish brown ; median dorsal part of the three rigid 
thoracic rings pale flavescent, prothorax with four black dots, two on each 
side of the median part, mesothorax with two marginal spots on each side 
of the median part ; metathorax with four similar spots but with a longi- 
tudinal median black band of the same colour, and a sharp keel in the 
posterior part. Head not broader than the prothorax, greatly retracted, 
and with the typical triangle in the anterior part ; the clypeus is narrower 
than in larva A and not pluri-grooved longitudinally; thelabrum is similar; 
the antennae are hardly distinct and show as a membranaceous cavity in 
which is imbedded a very short joint ; the three ocelli are less in a 
straight line than in larva A ; the three thoracic segments are corneous 
and rigid ; the four- jointed legs are robust, more so than in larva A, and 
the ungulate claw is stouter and more curved ; the orifices of the false 
legs are transverse and fringed with seriate, dark sub-compressed claws 
hooked outwardly and resembling cat-claws, they number from twenty- 
eight to thirt}^, and are more numerous on the upper margin, where they 
are continued inwardly, than on the lower. The body is glabrous, the 
prosternum and coxae have a single rigid seta on each side, and the raised 
hair-bearing areas on the upper side of the segments are not visible. 
This larva was dry and much contracted when I found it. It had 
emerged from the case of a ground-loving Psychid moth brought to me in 
a cardboard box. The presence of the ocelli show also that it is a second 
instar, or Caraboid larva. The shape of the orifices of the false legs and 
the disposition and number of the claws edging them are very different 
from those of larva A. It is also smaller, measuring only 9 mm. in length 
and 5 mm. in width.
