 without a recurrent nervure. Subcostal area with one basal 

 cell.

 on each side, hindward dull-red. Thorax with some tawny 

 marks. Legs whitish. Wings narrow, almost vitreous ; the 

 veins whitish ; fore wings pubescent ; veins rather few, with 

 brown points. Length of the body, 4-5 mm. ; expanse of the

Group TRICHOPTERA. 



In the caddis-flies the wings are generally hairy, with 

 longitudinal branching nervures, and but few transverse 

 nervules ; the posterior pair are generally larger than the 

 anterior, and folded longitudinally when at rest. The antennae 

 are setaceous, and the mandibles obsolete. The maxillary 

 palpi vary much, but are always 5-jointed in thefemale. The 

 legs are l6ng and slender, and the tibiae are often furnished 

 with spines in addition to the movable spurs which are found 

 at the apex and sometimes near the middle of each tibia. 

 These spurs usually differ in colour and appearance from the 

 spines, and are important characters in classification. The 

 formula 2.4.4. means that the fore tibia has a pair of apical 

 spurs, while the middle and hind tibiae have median pairs in 

 addition to the apical pairs. 



The neuration of the anterior wings is also very important 

 in classification, and the following remarks — taken from 

 Mr. McLachlan — may help the student. The anterior margin 

 is called the " costa." Parallel to the costa is a nervure 

 called the " subcosta." At the base of the wing the subcosta 

 emits the " radius," which runs parallel to it. Near its base 

 the radius emits the "sector," which divides into two 

 branches, each of which again divides. The space between 

 the two principal branches of the sector is closed by a trans- 

 verse nervule, and is called the " discoidal cell." Turning 

 now again to the base of the wing we find another longitudinal 

 nervure below the radius. This is the "superior cubitus,"
