Boopia is easily distinguished from Heterodoxus by the absence of 
the characteristic spines on the under side of the head, by the emargina- 
tion of head outline posterior to the eye, and by the truncated temporal 
lobes. Twelve species are known to us at present, including the dubious 
B. peregrina ; of which, in this communication, we redescribe B. notafusca 
of Le Souef, and describe three new species. 
Boopia notafusca Le Souef. Figs. 5-6. 
Le Souef (1902, p. 50, Fig. 1) has given a summary description and 
a figure of no diagnostic value of this species. Our figures have been 
prepared from his type. Fig. 5 shows the character of the head and 
thorax, and serves to illustrate the genus as well as the species. Fig. 6 
is an uncorrected camera drawing of the type d- 
Description of <$. Head broader than long, with very square temporal 
lobes, the posterior temporal angles, in specimens not subjected to com¬ 
pression, projecting behind the occiput. Eye large, simple. Prothorax 
two-thirds as long as wide, with lateral angles at about the middle of 
its length, narrow anteriorly and posteriorly. Mesothorax short, with 
lateral prominences bearing stout spines. Metathorax the width of the 
prothorax, widest close to its hind margin, shorter than the prothorax, 
with rounded angles. Abdomen broadly ovate, widest at the fourth 
segment, terminating in a narrower roundly conical last segment. Legs 
long, the second tarsal joint especially so. This joint exhibits a delicate 
transverse ridging upon its inner face, and is without an appendage. 
The general nature of the chaetotaxy will be apparent from the figures. 
The ? differs from the d only in being slightly larger, and in the 
posterior end of the abdomen, which shows two curved gonopodial 
processes.

The species thus briefly characterised falls into that group within 
the genus which has hairs only, and no spines, upon the occiput. In
