to separate M. gallica Sim. and M. sundevallii W'estr. are found 

 in the genitalia of both sexes. 



Maso gallica Sim. Figs. 17 to 20. 

 Male. • Fig. 17 and 18. 

 PALPUS. Tibia above with a shallow depression at apex,, 

 the external angle of which is rounded and the internal 

 angle prolonged into a depressed, blunt, black-tipped 

 apophysis, at the base of which are three club-shaped 

 bristles. 



Tarsus. — Base drawn out into a conical elevation on the 

 top of which are three club-shaped bristles. 

 In NI. siindevallii Westr. the palpal tarsus is not drawn out 

 at the base, the tibia is not excavated, and has no apophysis,, 

 and the peculiar club-shaped bristles are entirely absent. 



Female. 



EPIGYNE, figs. 19 and 20. A low semi-circular transverse 

 projection, having on each side a black horny space, and 

 in the middle a slender, shortish cylindrical process, some- 

 what raised and directed obliquely backwards. 

 In the epigyne of M. sundevallii Westr., this raised oblique 

 process is wanting. If a comparison be made between the 

 present drawings and the figures of the latter species given in 

 The Naturalist ,June 1910, p. 229, fig. 2, epigyne, fig. 3, male 

 palpus, the distinction between both sexes of the two species 

 will be clearly seen. 



Neon valentulus sp. nov. Adult males 1.9 to 2.5 mm. ; 

 adult females 2.2 to 2.8 mm. 



Male. 



CEPHALOTHORAX very obscure yellow brown, very strongly 

 suffused with black towards the margins, especially in 

 front, with darker radiating lines behind and on the sides, 

 and a strong black marginal line ; the front and sides 

 of the caput with a black band dilated around the dorsal 

 eyes, and marked with stronger and more bristly hairs 

 on slightly raised bases. Tegument of the caput somewhat 

 rugose. 



Eyes. — Those of the third row as large as the laterals of the 

 first row, and as widely separated so that the dorsal eye 

 quadrilateral is parallel-sided. Face eyes straight by 

 summits, contiguous and surrounded by white hairs. 



Clypeus narrower than the radius of a front central eye, 

 blackish, with a cluster of a few long slender incurved 

 bristly hairs projecting outwards from its centre.
