sina railed Tapinocephali, as Nemesia, being related to the genera above 

 mentioned represents the passage from the Aepycephali to the Tapinoteph- 

 a!i. The generic characters given by Ausserer 1 however easily distin- 

 guish it. 



Neinrsiii. "Head low, little elevated above the thorax. Depression with the 

 concavity behind." 



The specimen of Nemesia caementaria winch 1 saw in the Museum 

 of the Boston Soc. of Nat- Hist is readily distinguished generically from 

 this. 



i. Myrmekiaphila foliata, n. sp. 9 5 specimens. (PI. V, figs. 6, 7, 12, 14, 

 and 22. ) 



In addition lo the generic characters are the following specific characters. An 

 lerior central eyes 2 situated from each other about one diameter. Posterior lateral 

 eyes a little larger than the ant-centrals. Post-centrals slightly angulated, a little 

 smaller than the ant-centrals, each one about a diameter distant from the corres- 

 ponding post-lateral, and situated a very little cephalad of the base of rectangle 

 bounding the lateral eyes. Ant-centrals on point of hill higher than the others. 

 Ant-laterals lowest; these and the post-laterals situated at base of the low hill for 

 the eyes. 



Legs of one of largest specimens. 4th, 21 mm. 3d, 14J mm. 2d, 16 mm. 1st, 

 17 mm,, palpus 11.5 mm. Ceph'x 9x7 mm. 



In the anterior radial lines, on each side of the caput is an elongated shallow 

 depression. Two lateral radials on each side show a long, narrow, shallow depres- 

 sion, post radials indistinct in some. Edges of ceph'x slightly crenate, and showing 

 shallow, irregular depressions: posterior margin emarginate. Caput 3.5 mm, eleva- 

 ted above thorax. 



Sternum 5 mm long by 3.75 mm broad, broadest part one-third distance from 

 posterior end, distinctly angled. Labium slightly emarginate. Abdomen IO mm 

 long by 7 mm broad. 



Armature. Very few hairs, more perciptible on abdomen, and still more so on 

 the three and four distal joints of the legs, where the hairs are darker. Tarsus IV 

 one or two spines on anterior side. Metatarsus IV with four or five long spines on 

 under side, distal end 1 or 2 near centre. Tibia IV with scattered stiff hairs. Patel- 

 la IV, upper and anterior side with numerous slender spines, with quite a strong base. 

 A broad longitudinal denuded space on upper side, divides this patch of hairs. Fe- 

 mur IV with a number of spines on distal upper end. Tarsus III, 2 spines on under 

 side. Metatarsus III, 1 or 2 spines on under, distal end, 1 or 2 more near middle: 

 two rows 3 or 4 spines each on upper anterior, and posterior edge. Upper surface 

 of tibia and patella III, covered with spines, which are divided into two patches by an 

 oblique, denuded, narrow space, Tibia III, shorter than patella III. Tarsus II, 1 

 or 2 spines on posterior under edge; metatarsus Hand 1 with 2 or 3 spines on under, 

 distal end, and 2 or three near middle. Dense row of hairs on anterior and posterior 

 side of tarsus and metatarsus I; palpus, tarsus as in I; tibia with spine on under 

 distal end, and one or two near middle. Labium separated from sternum by a deep

2 It seems unnecessary to repeat the description of the eyes so far as given tor 

 the genus. Some variation should, however be allowed for other species which may 

 be found.
