Pi/cnoscelus (?) gardneri^ sp. n. (Blattidtii). 



Tegmeii about 30 miu. long and 12 broad ; uiargiual field 

 broail, with elevated and broadly rounded base, tlie width 

 (dtpili) of the Held near base 3 mm. ; subeosta and branches 

 of radius very oblique ; subcosta running j)arallel with first 

 branch o£ radius (its total length from base of tegnien 

 12'7 mm.), giving off a branch about 'i'2 mm. from end, and 

 another, rudimentary, one about 1"5 mm. earlier; radius with 

 very numerous superior branches, first simple, second and 

 third with long foiks, fourth with short fork, fifth witii two 

 long branches, sixih and seventh each with a lung fork, the 

 forked branches with long stems ; radial sector arising about 

 ll'O mm. from base of tegmen ; media and cubitus between 

 them with about nine principal brancheSj between which are 

 conspicuous supplementary veins ; cross-veins present. The 

 inferior basal area of tegnieu is lust.

This agrees with the modern Pycnoscelus surinarnensis (L.) 

 in the broad marginal field, general size of tegmen, two- 

 branched subcostn, general character of branches of radius, 

 early origin of radial sector, and numerous branches of media, 

 with supplementary veins between. There are no visible 

 differences which could possibly be regarded as of generic 

 value ; but as we have only an inconifjlete tegnien, the generic 

 reference must be considered provisional. Tiie amber Blattida; 

 are very different. 



AUopterites (gen. nov.) multdineatus, sp. n. (Gryllidie). 



Lower wing as preserved li< mm. long, but probable total 

 length about 23 mm. 



Costa nearly straight; subcosta, radius, and media running 

 parallel below it, the intervals between then) less than the 

 width of the veins; media giving uff" very numerous (many 

 more than in Qryllus) oblique branche.<, which are diiocted 

 toward the apex of the wing ; all these veins are ferruginous 

 as preserved, and the branches of the media are obli(juely 

 crossed by numerous (four in 2 mm.) continuous veins of the 

 same colour, directed upward and outwanl (like the cross-veins 

 in Mantoida), forming angles of about 45° with the brandies. 

 These oblique cross-veins abruptly cease at the lowest branch
