1 6 THE BLATTIDAE OF PANAMA 



The length from occiput to apex of tegmina ranges in the series 

 from 5 to 5.8 mm., the smallest examples being males. The body 

 length averages 4.5 mm. in the males, 5 mm. in the females. This 

 agrees with Brunner's diagnosis of what he believed to be the female 

 type, but is larger than the dimension given that specimen by Bur- 

 meister. In general coloration the great majority are shining 

 blackish brown, the remainder vary to as light as amber brown. 

 These paler examples may very possibly have been captured before 

 they had fully hardened and consequently before they had reached 

 their normal adult depth of coloration. 



In the present species the costal veins are distinctly clubbed dis- 

 tad; this is not true of the closely related A. fallax. 



Ootheca. — One female is at hand with ootheca almost fully ex- 

 truded, carried with suture dorsad. This ootheca closely resem- 

 bles that discussed under A. hemiscotia, here described, differing 

 only in having the suture even higher, its height equalling nearly 

 half the distance from its base to the ventral margin, and with 

 dorsal surface of suture more finely sculptured in similar fashion. 

 It will be noted that this is a type of ootheca very widely dis- 

 tinct from that of Lissoblatta fulgida (Saussure) . 

 Anaplecta asema^ new species (Plate II, figure 5). 



Apparently related to A. azteca Saussure,^ differing in the cephalic 

 coloration, tegminal apices, which are slightly more acute, and 

 slightly shorter wings with different coloration of area of costal 

 veins and of branches of axillary vein at base of appendicular field. 



Type. — 9 ; Gatun, Canal Zone, Panama. July .25 to 31, 1916. 

 (D. E. narrower.) [Hebard Collection, Type no. 431.] 



Size small, form moderately slender as in azteca. Head distinctly longer than 

 broad; interocellar area forming, with margins of ocellar areas, a decided projecting 

 but rounded ridge above each antennal socket; ocellar spots distinct. Pronotum 

 rectangulato-oval, narrowing very slightly more cephalad than caudad; surface 

 weakly convex, showing moderate latero-caudal flattening of the disk. Tegmina 

 narrow, costal margin weakly convex to the sharply rounded apex; costal veins 

 numerous (ten), simple; discoidal sectors few (four).^ Wings proportionately 



^ From ao-TjAta = without distinctive marking. 



' A series of this species, including topotypic material, is before us. 



' In all of the American species examined these sectors are longitudinal and composed 

 of the median vein with one to three rami, and the ulnar vein, sometimes with one ramus, 

 except in A. domeslica Saussure and Zehntner and A. cabimae, here described, in which 

 the median and ulnar veins have no rami.
