Garijpus L. K. (cf. pi. II, fig. 1 a and fig. 14, p. 90). The (üfFercnccs between the two 

 genera, wliich are found in the hairs, wliich are pointed in Olpiiim L. K. and at 

 least partly short and obtuse in Gargpus L. K., as well as those found in the polished 

 skin of the former and the granular of the latter seem to be pretty constant. In 

 the structures of the antennae we find no absolute characters, but some of relative 

 value; the galea of Garypns L. K. is either a simple stylet or a well branched organ, 

 while it in Olpiiim L. K. is most often threedivided; the serrula of Garypus L. K. 

 has either the basal teeth enlarged in a remarkable manner (cf. ])1. II, fig. lb— 2a) 

 or has the median teeth shortest, increasing gradually in length both towards base 

 or tip (fig. 4 c, pi. II): in the other genus we have only the basal tooth somewhat 

 enlarged and longer, while the remaining are of equal length (cf. p. 17). In the 

 palps no absolute characters are found in the comparative length and breadth of 

 the joints, but it is nevertheless interesting to notice, that the femur is at least 

 three times as long as broad, and that the fingers are longer than the hand in 

 Gargpus L. K., while the palps of Olpium L. K. are sometimes long and slender, 

 sometimes short and clumsy; the femur of the latter genus bears a dorsal „tactile" 

 hair near to the base. The coxae of Garypus L. K. are as a rule longer and more 

 slender than those of Olpium L. K. While the basal portion of the femur of the 

 first pair of legs always seems to be widened out towards the tip, to be at least 

 twice as long as the depth, a little deeper and one and a half times longer than 

 the tibial part in Garypus L. K., the shape of and relation between these joints 

 show in Olpium L. K. all kinds of variations; the articulation between the two 

 femoral parts is in the former of these genera always a hinge-joint, while it in 

 the latter is not always so (cf. p. 38). The tarsus of the first pair of legs seems in 

 Garypus L. K. never to be shorter than the tibia, while it is often so in Olpium L. K. 

 A tarsal "tactile" hair is wanting in Garypus L. K. From the above it may be 

 realised, that Garypus L. K. is much better characterized than Olpium L. K., as 

 many organs show marked variations in their structure in the latter genus, while 

 they are pretty constant in the former. The species of Garypus L. K. naturally fall 

 into two groups, the differences between which will be discussed later on; Olpium 

 L. K. (in the wider sense) has lately been subdivided into four genera namely the 

 Olpium L. K. proper, Minniza Sim., Amblyolpium Sim. and Garypimis Dad.; the 

 value and characteristics of these genera we are now going to discuss. 



The genus Minniza Sim. is according to Simon characterized in the following 

 manner (1881. 39. p. 14). "Genere Olpio affinis, sed cephalotliorace multo longiore 

 quam latiore, piano, antice hand convexo, oculis a margine cephalothoracis hand 

 separatis, abdomine longissimo vermiformi, omnino membranaceo"; in the descrip- 

 tion of M. vermiformis Sim. he adds "hand striatus". The same author gives the 

 following description of Amblyolpium Sim. (1898. 52. p. 3). "Voisin des genres Olpium 

 et Minniza, dont il diffère a première vue par son céphalothorax trontjué droit en 

 avant aux niveaux des yeux, qui occupent ces angles antérieur, tandis (pie dans les 

 genres citées, le céphalothorax est prolongé en avant des yeux en une sorte de
