Figs. 21-28. _able Dr. Chamberlin's descr.iptions of this species are found to be accurate. However, lam to point out that the that 1R Philippine forms show a slight variation from the Borneo type, in the former there are of the only six to seven finer transv.erse sulci behind the front margin second plate instead of nine or ten. And while Dr. Chamberlin described the male only, I have with the had the opportunity of examining the females. In these the vulva is squarish in shape, lies on the inner side of the vulva as operculum than the and the larger genital opening bursa, figure 25 Ocelli seven in number and in one single row. I examined 11 specimens, 5 males and 6 females. Their measurements are as follows: total length: males from 15.5 to 24 mm., average 18.3 mm., females from 11 to 22 mm., average 17.6 mm.; length of head, males from 2 mm. to 3 mm., average 2.6 mm., females from shown in .. 1.5 mm. to 3 mm., average 2.6 3 mm. to 3.5 mm., average mm.; width of head, males from 3.1 mm., females from 2 mm. to 3.5 mm., average 2.9 mm.; length of collum, males from 2 mm. to 3 mm., average 2.2 mm., females from 115 to 2 mm., average 1.9 mm.; width of collum, males from 3 mm. to 4 mm., average 3.4 mm., females from 2 mm. to 4 mm., average 3.4 mm.; length of second plate, males from 2.4 to 3.5 mm., average 2.8 mm., females from 2.5 to 3.5 mm., average 2.8 mm.; width of second plate, males from 9.5 to 12 mm., average' 10 mm., females from 6 to 12 mm., average 9.8 mm.; length of pygidium, males from 3.5 to 5 mm., average 4 mm., females from 2 to 4 mm., average 3.S.mm.; width of pygidium, males from 6.5 to 10 mm., average 7.5 mm., females from 4 to 9 mm., average 6.8 mm.; length of antennae, males from 2.5 to 4 mm., average 3.5 mm., females from 2 to 4 mm., average 3.25 mm.; length of the first pair of legs, males from 3 to 4 mm., average 3.3 mm.; females from 2.5 to 4 mm., average 3.25 mm.
