Species. By R. I. Pocock. 
[Plate IV. } 
Genus GALEODES. 
The species of this genus seem to me to be but little under- 
stood. ‘hat ‘there is a large amount of variation in the 
genus can be observed by anyone who works through a mass 
of material from various localities; but it is very difficult to 
find the specific characters that obtain consistently in indi- 
viduals of all ages and both sexes. 
The adult males and females (at least of some species) 
appear to be recognizable by the following characters :— 
9. Head larger, to support the larger strongly toothed 
mandibles, which have no flagellum and no spiniform hairs. 
Palpi shorter as compared with the width of the head and 
slighter; legs also shorter, the tarsi of the fourth normally 
clothed below with simple hairs. Malleoli shorter and alto- 
gether smaller. The two halves of the genital operculum 
enlarged and united across the middle line to form a single 
large plate. There are no peculiar bacilliform hairs on the 
abdomen. 
6. Head narrower, to support the smaller weakly toothed 
mandibles, which are provided with a flagellum and with a 
large number of erect spiniform hairs to protect the flagellum 
when atrest. Palpi longerandstouter. Legs longer; tarsus 
of the fourth clothed below with modified hairs. J/alleoli 
longer and larger. The two halves of the genital operculum 
distinct, with two smaller plates appearing in the middle line 
between them. The fifth and often other sternal plates of the 
abdomen provided with modified bacilliform hairs. 
Male examples have been described without the hairs on 
the fourth tarsi and on the abdomen. It is not certain, 
however, I suppose, that these male examples were mature. 
Moreover, the shape of these hairs has been used for distin- 
guishing species; but an examination shows that in some 
individuals no two of the abdominal bacilliform hairs are alike, 
and that they vary on the same sternite from being short and 
stout to long, slender, and cylindrical. On the fourth tarsi, 
too, the hairs have sometimes blunt points, sometimes filiform 
points; but it seems highly probable that the latter kind is 
transformed into the former simply by the process of wear.
