group Aepycephali. It can, however, be separated easily 

 from these genera by the following characters/ 



Aepyeephahis. ' Head high and somewhat pointed, ceph'x broad as 

 long, side e}es form a trap-zium, lip broad as long, etc." 



Vteniza "Side eyes from a trapeziimi. Lip somi what three cornered, 

 spinnerets short ami thick Abdomen great, eggforme 1, etc." 



Cyrlocfirenum. ' Ceph'x as m ( ^e7ai:a ; but head broader in front. Eyes 

 occupy whole breadth of head, a'^dom ;n and spinnerets as in Cienua, 

 etc." 



Ci/r(auchenhis. "Foim of Ceph'x, ana position ol eyes as in Oyrioca- 

 rertLtn^ maadibits nut drawn int) a point, etc." 



As the nesting and food habits singularly resemble those 

 of members of the genus Nemesia, and the form of the abdo- 

 men also, it might be confounded with that genus, which be- 

 longs to the group of TherapJiosinae called Tajn/ioccpludr^ as 

 Nemesiai, as being related to the genera above mentioned 

 represents the passage from the Aepycephali to the Tapino- 

 cephalL The generic characters given by Ausserer*'' however 

 easily distinguished it. 



JVcmeMi, "Head h)W, little elevated above the thorax. Depression 

 with the concavity behind " 



The specimen of Nemesia caementaria which I saw in the 

 Museum of the Boston Soc. of Nat. Hist, is readily distin- 

 guished generically from this. 



1 . Myrmekiaphila f oliata, n. sp. female 5 specimens. (PI. V, figs. 

 6, 7, 12, 14, and 2z ) 



In addition to the generic chiracters are the following specihc charac- 

 t-TS Anterior ceotr il eyes'* situate 1 from each other aboui t)ne diameter. 

 Posterior lateral eyes a little larger than the ant-centrals. Post-centrals 

 slightly angulated a little smaller ihan the ant-centials, each one about a 

 diim^iter distant from the correspondinij: post lateral, and situated a very 

 litle cephalad of the base of rectangle bounding the lateral eye?. Ant 

 centrals on point of hill higher than tbe others. Ant-laterals lowest; 

 th^se and the post-laterals situated at bnse of the low hill for the eyes. 



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

 mm 1st, 17 mm., palpus il 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, nar- 

 row, shallow depression, post radials indistinct in some Edges of ceph'x 

 slightly crenate, and showing shaUow, irregul-ir depressions: posterior 

 margin emarginate. Caput 3.5 mm. elevated above thorax. 



Sternum 5 mm. long by 3.75 mm. broad, broadest part one-third dis- 

 tance from posterior end, distinctly angled. Labium slightly tmarginate. 

 Abdom m 10 mm. long by 7 mm .broad. 



Armilure. Very few hairs, more perciptible on abdomen, and still 

 more so on th i three and four cistal joints of the legs, where the hairs are

^ It seems unnecessary to repeat the description of the eyes so far as 

 given for the genus. Soma variation should, however, be allowed for 

 other species which may be found.
