to use to advantage. It is thus probable that their love-song is a 

 gnashing of teeth. 



This solitary existence, at least during the day-time, accounts pro- 

 bably for our lack of knowledge in the distribution of the species, but 

 I still believe it to be restricted, and the number in kind comparatively 

 small.

MAXENTIUS CANUS, n. sp. 



In spite of a less elongated appearance due to a more regularly 

 globose abdomen this species may be included in the genus, from which 

 it differs in having three sharp equi-distant spines in the upper side of 

 the fore tibiae instead of two. In life it is almost sem.it ransparent 

 white, with the apical part of the spines and spurs slightly fuscous ; 

 the body is smooth, on the labrum and the maxillary palps are a few 

 rigid setae ; the abdominal edge of the sub- genital lamina, the legs, 

 and tarsi are bristly, the hairs, especially on the legs, are stiff. 



Length of body 35 mm , of pronotuni 7 mm., of posterior femora 

 and tibiae 17 mm., respectively. 



Intermediate in form between M. repens, Stal, and the more elongated 

 M. fuscofasciatus, Stal. The three first abdominal segments on the 

 sides of the dorsal part are quite smooth. 



The male example in the Collection was dug out from a depth, it is 

 alleged, of sevei'al feet in the wet sand of the sea shore at Port Nolloth, 

 Cape Province. 



GEN. NASIDIUS, Stal. 

 Bih. Svensk. Akad. iv (5), 1878, p 51. 



The characteristics of the species on which Stal founded this genus 

 are the enormously massive development of the head, the somewhat 

 short antennae, which should really read : antennae as long or slightly 

 longer than the body ; fore tibiae with two spines on the middle of the 

 upper side, and one at apex, and in the female a very short but robust 

 ovipositor. 



The presence of one or two spines at or near the median part of the 

 fore tibiae seems in this case to vary specifically, for there is a species 

 so closely related to the type species of the genus, i. e. N truncatifrons, 

 that, but for the difference in the number of spines, the males of the 

 two species could be distinguished with difficulty.
