meso-thorax, and a third the meta-thorav. All three are distinct, and each 
bears a pair of legs. 
The Pro-thoraz.—This is the largest of the three thoracic segments. It 
partly encloses the head, and viewed laterally with a high-power lens shows 
the following folds :— 
The scwtellar fold, taking up almost the whole of the dorsal and lateral 
regions. 
The pedal fold, which lies just below it and partly conceals the foot. 
The scutellar fold of the pro-thorax bears no spines but is sparsely 
covered with hairs. It bears a pair of spiracles, one on each side, on its 
posterior margin just above the pedal fold. 
The Meso-thorax.—This differs from the pro-thorax in that it is smaller 
and shows four folds. 
The scwtellar fold is present as before. 
The epi-plewral fold is a small fold lying below the scutellar fold. 
A pedal fold is present as before. 
The prescutal fold is the fourth fold, small and narrow, lying dorsally 
and adjoining the scutellar fold anteriorly. 
No spiracles are present on the meso-thorax. 
The MMeta-thorax resembles the meso-thorax except that the prescutal fold 
bears two rows of stout spinules, which curve backwards and resemble a bent 
collar-stud. These spinules are undoubtedly of use in locomotion, and, 
according to Perris, are peculiar to the Anobiid larva. The meta-thorax bears 
no spiracles. 
The Abdomen. 
The first eight abdominal segments are similar. Viewed laterally under a 
high-power lens they show four folds, a prescutal, a scutellar, an epi-pleural, 
and a hypo-plewral fold which lies below the epi-pleural fold, and takes the 
place of the pedal fold of the thoracic segments. 
The prescutal folds of the first eight segments of the abdomen bear two 
rows of spinules, and the scutellar folds a pair of spiracles. The spiracles are 
indistinct and appear to be unprotected by any external structure. The 
arrangement of the spinules on the folds of the abdominal segments varies 
with the species. The 9th abdominal segment is the largest of all; it has 
no prescutal fold and carries no spiracle. The 10th abdominal segment is 
not visible laterally. It is represented by three folds surrounding the anus as 
before stated.
