collected in the Lagos district by W. A. Lamborn. — 521 
thorax in front of the transverse suture with four dark-brown or 
blackish stripes of which the median pair are the broadest; the 
median pair of stripes behind the suture pale brown; the second 
pair of stripes dark-brown or blackish, narrowly ovate and 
attenuated anteriorly; the third pair of stripes are also very broad 
but of the same colour as the ovate ones. 
Matz, closely resembling the female in colour and markings. 
Genital armature (fig. 2) with the superior claspers widely divergent 
dorso-ventrally, with the inner lateral margin strongly concave, and 
the outer lateral margin angulate near the middle, tips bluntly 
rounded. Vesica (fig. 2b) very short and arising from an almost 
complete chitinous ring through which the penis (fig. lc) passes. 
The latter curved suddenly downwards and forwards, base bulbous ; 
inferior claspers (fig. 2d) wide and broadly rounded distally, lower 
margin strongly concave; median process (fig. 2e) obliquely truncate 
distally. 
Taking all the salient characters into consideration it 
would seem that this insect agrees best with the genus 
Rhinopsylla, Riley, as defined by Crawford * in his article on 
the American Psyllidae; though, as this author has pointed 
out, this genus may eventually prove to be identical with 
the European Bactericera, Puton. The head of R. lamborna, 
Newst., 1s not, however, so strongly birostrate as in the 
American species, but this character varies to a somewhat 
marked extent even in the few known species described 
from that country. 
I have much pleasure in dedicating this insect to its 
discoverer. Described from 6 9g and 8 99. The type 
male and female bear the following data :—‘*‘ A in cop. B. 
B in cop. A. Feb. 26, 1912. Lagos, 70 m. EH. nr. Oni 
clearing. Dry 8.c. Dec. 8-11 to Mch. 23, 1912. W. A. 
Lamborn.” The paratypes (now mounted in Canada 
balsam) bear the record :—‘‘ Fr. mass like 61. Feb. 25, 
1912. Lagos, 70 E. Oni clearing. Dry Seas. Dec. 8-11 
to Mch. 23, 1912. W. A. Lamborn.”’
