from Funafuti (cf. 53, p. 321) and found it difTL-renl from the the two other species 

 in the structure of the serrula exterior (tig. 3, p. 17) thereby, that the penultimate 

 tooth is not free and pointed, but like the preceding ones. G. minor L. K. and G. 

 nigrimanns Sim. are probably similar to the already described in all characters of 

 more importance. G. Cuyahaniis Balz.') differs in different respects; the galea of 

 the female is fairly long, clumsy and provided with several teeth distally (46. 

 lav. XVI, fig. 22 a), while that of the male is a pointed, simple fairly short stylet; 

 the basal tarsal joints of the legs are longer than the distal, and the tarsi of the 

 two last pair of legs are a little shorter than the tibia. 



The second group, of which G. sa.vicola Wath. and G. Floridensis Bks. are the 

 only specimens examined, is characterized in the following manner. The cucuUus 

 is not sharply set off behind, fairly broad in front, with median incision of front 

 margin shallow and longitudinal groove behind poorly developed. Céphalothorax 

 a little broader behind than further in front, slightly or even much longer than 

 broad; of the two cei)halothoracic stripes the median is wanting or indistinct, 

 while the posterior is very well marked. The flagellum (PI. II, fig. 4 b— 5 a) of 

 the antennae consists of three simple or pinnate hairs; the galea is widened 

 out towards the end with numerous terminal branches in the female (fig. 4 c). 

 The serrula exterior with the median teeth the shortest, increasing in length to- 

 wards base and tip; the basal tooth is not enlarged distally and the terminal not 

 free and pointed. The lamina interior consists of a great number (about 25) of 

 rather narrow, not marginally serrated teeth (fig. 4 a). The manducatory part of 

 the maxillae gradually merges into the maxillae proper (fig. 15, p. 92). The tibia 

 of the palps bears anteriorly just beyond stalk no low eminence. The coxae are 

 long and slender; the fourth pair is at least 13 longer than the third and 33 

 longer than broad. The first tarsal joint is much longer than the second; the tarsi 

 of the fourth pair of legs much shorter than the tibia (figs. 9 a-b, p. 41). It seems 

 pretty sure that at least G. Beaiwoisii Sav., which is nearly related to if not iden- 

 tical with G. sa.vicola Wath., and G. lilloralis L. K. in all points of greater interest 

 will show similfirity of the two previously mentioned species. G. men'rfjo/iaZis Can.(V), 

 G. Hnngaricus Tom. and G. Senegalensis Balz, probably belong to the same group. 



G. Canariensis Tull. and G. latus Hans, are in some featuies more like to the 

 first group viz. the presence of a distinct median stripe and an indistinct posterior, 

 but in others more similar to the latter, viz. structure of the galea. As not even 

 the description of G. grannlatiis Bks. is known to me, it is of course impossible to 

 say anything about its systematic position. 



The female of Ganjpiisirriigaliis Sim. bears in similarity to many other species 

 belonging to widely different genera like Chclifer Geof., Pscndochiridiiini claingeriim 

 Thor., Obisium inuscorum C. K. and Ghthonius C. K. an egg-ball beneath the base of 

 the abdomen; the young embryos take their nourishment from their mother and

 of minor dilTerences referred to G. Cuijabanus lialz. ^4(i p. 441).
