little creature’s body ; they undergo no metamorphosis. 
though they differ from the adult, 
in having a broader head and 
shorter and thicker antennse. They 
attain their full size in eleven 
weeks. Fumigation with brim¬ 
stone, thoroughly done, is the 
best cleansing of rooms troubled 
with these pests. Of the Re - 
duviidce , I shall mention only 
the Reduvius person at us, “the

its habit, in its larval stage, of covering itself with dust, 
thus disguising its real self. It is said to be a devourer 
of its relative, the Bed-bug; if so, all honour to Reduvius! 
The Lygceidcu are for the most part small insects, 
being often marked with red, black, and white spots. 
The family, like that of the Coreidcv, are distinguished 
by longitudinous veins in the membranous portion of 
the wings. Lygocus equestris is one of the most con¬ 
spicuous species. 
The Homoptera, the other sub-order of the Rliyncota , 
contains those suctorial insects whose fore-wings, 
whether thickened or membranous, are of a similar con¬ 
sistency throughout. In the common little Frog-hopper 
(.Apliropliora spumaria ) we have an instance of 
thickened fore-wings homogeneous throughout, the hind 
wings being membranous throughout; in the Aphides 
or Plant-lice the two pairs of wings are membranous 
throughout. The sucking apparatus in the Ilomoptera 
springs from the base of the head, very far back near
