56 Laseola erythropus Sim., with a Key to British Laseolae. 
Female, length 2.4 mm. Figs. 9 and 10. 
Cephalothorax longer than wide, rising gradually from the 
posterior margin ; the caput elevated, convex and evenly 
curved, with black bristly curved hairs on the fore part 
directed forward, some of them forming a central longi- 
tudinal line which anteriorly passes between the posterior 
central eyes. Colour, yellow brown, suffused with black, 
especially towards the front, where there is a number of 
roundish yellow brown spots. 
Clypeus, high, deeply impressed below the eyes, and then 
inclined gradually forward to the lower margin ; with 
upturned hairs and spots similar to those on the cephalo- 
thorax. 
Ocular Area, blackish, prominent. 
Eyes, eight, in two rows, all pearly white except the anterior 
centrals which are dark, moderate in size. 
Posterior Row, viewed from above, curved forward, eyes 
sub-equal, the centrals distinctly nearer to each other 
than to the adjacent laterals, the former being fully one 
diameter apart and close on one and a half diameters 
from the latter. 
Anterior Row, viewed from the front, strongly curved 
backwards ; the centrals somewhat the larger, widely sep- 
arated from each other on a rounded prominence, but 
rather close to the laterals. The central eye space is 
thus much wider in front than behind. 
Palpi and Legs, light yellow-brown (see p. 5 7) ; the latter, 
order of length, 1, 4, 2, 3, being long, fairly strong and 
provided with hairs only, and without darker markings. 
Maxillae, Falces and Labium, dull yellow-brown, suffused 
with black, provided with strong black pubescence and 
showing numerous yellow-brown spots. 
Maxillae, wide below, acuminate towards the apex, and 
converging round the labium. 
Falces short, weak, acuminate ; fang groove without teeth, 
but with a marginal line of stiff black hairs externally. 
Labium, short, semi-circular, much wider than long, flat, free. 
Sternum, dark brown, smooth, shining, convex, much longer 
than wide, its surface set with numerous yellow-brown 
spots and black, upturned hairs. 
Abdomen, black, short, oval, very convex, both surfaces 
closely covered with minute punctures, and short equal 
hairs ; the sides and under surface with small, roundish, 
yellow-brown spots. 
Epigastric region and spiracular opercula, dusky j 
yellow-brown.
