ANiTALS OF THE TkAJTSVAAL Mi[JSEU:M. 



133 



separated hy deep grooves, punctuations unequal, the large ones very large 

 and deep, in the marginal grooves they may be contiguous or almost so^ 

 they prolong the marginal groove anteriorly beyond the eyes by two lines of 

 punctures, the remainder are arranged in four more or less regular, longi- 

 tudinal lines in the middle area of the shield, the small punctures are evenly 

 distributed over the shield, but distant from each other, and usually so fine- 

 and shallow as to be almost invisible : three posterior longitudinal grooves,, 

 very superficial ; dorsal porose areas present at anterior quarter of length 

 of shield. Ventral surface yellowish or brownish in colour ; a few 

 punctures ; glabrous or with thinly scattered hairs ; sexual orifice opposite 

 the anterior edge of coxae II, sexual grooves diverging behind ; anus 

 chestnut brown in colour, opposite the middle of the anal plates, which are 

 triangular, with the inner edge concave, outer, edge convex, and posterior 

 edge convex (/A', f) ; a chitinous point forms the accessory anal 

 plates ; eleven festoons present, tlie median one often i)rolonged in 

 rectangular appendage ; stigmatic plates elongate, comma-shaped. 

 East rum with base wider than long ; depressed in middle, the 

 posterior angles prominent, lateral angles prominent at the 

 anterior third of tlie length ; mandildes (.Y. /) witli process of 

 inner apophysis transverse and l)identate, outer apopliysis l)identate, the 

 anterior tooth small ; hypostome witli six rows of teeth ; palpi longer than 

 wide, article II longer than article III, its inner dorsal margin longer than 

 the outer ; seven to nine hairs on the inner ventral margin ; article I also 

 with a ventral projection ; article III wider than long. Jjer/s reddish 

 brown m colour, strong ; articles s<unewhat flattened dorso-ventrally ; 

 tarsi short. 



Female. — Bodi/ oval, a little wider l)eliind than in front, may reach a 

 length of 1:^ mm. by 8.;) mm. wide ; colour l)rownish, with lighter colour 

 marking the furrows and festoons. Shield {X, f) scarcely or not longer than 

 wide ; very dark, almost black in colour ; shining ; sides rounded or only 

 slightly angular ; punctuations numerous, unequal, large punctuations in 

 middle and marginal areas ; marginal grooves formed of a row of large pits, 

 small pits event}' distributed, but usually so small and superficial as 

 to be almost invisible ; cervical grooves almost reach the posterior margin 

 where they nearly join the marginal grooves ; eyes shiny, flat, pale yellow, 

 or often reddish in preserved specimens, a little behind the micklle of the 

 length of the shield. Dorsal surface of the abdomen, lightly shagreened, 

 in young individuals, punctuations large and occupied by whitish hairs ; 

 dorsal porose areas just posterior of the sliield ; marginal grooves at some 

 distance from the margin, occupied by punctuations and hairs ; four 

 anterior grooves, the outer ones close to the corresponding marginal grooves 

 and very long ; three posterior grooves, the median longer ; festoons well 

 marked, elongate ; when fully engorged the grooves and festoons are still 

 faintly marked, usually by lines of a grey colour. Ventral surface of a 

 uniform greyish or brownish colour, lighter than tlie dorsal surface : 

 glabrous or with a few hairs ; ])unctuations few and scattered ; ]:)osterior 

 festoons very a])]^arent ; sexual orifice opposite first inter-coxal space, 

 sexual grooves diverging very rapidly behind coxae TV ; anal groove well 

 marked ; ano-marginal groove ])resent ; stigmatic plates short, comma- 

 shaped, with prolongations very short. Bostrum with base shorter than in 

 mal^ ; mauflihles (A", /') with i)rocess of inner apophysis hearing four teeth, 

 outer apophysis tridentate ; hypostome as in male, hut lono-er ; ])alpi similar 

 to tliose of tlie male, only longer. Legs similar to those of the male, exceiit 

 that they are lon^-er and more slender : tarsi relatively long.
