Color. — The present specimens have immaculate tegmina. A 

 Guatemalan series of twenty-four specimens, at hand, shows all 

 the transitions from this type to the one having the tegmina heav- 

 ily marked with two distinct transverse dark nebulous bands. 

 This variation was also noted by the original authors. 



Ootheca. — A female, with ootheca slightly less e.xtruded than in 

 the specimen of L. fidgida discussed, is before us. In the present 

 case the suture is dorsad. The structure of the ootheca is very 

 similar in these two species. The position in which the ootheca 

 is carried would, from this evidence, again aj^jx'ar to ha\e little or 

 no significance in systematic work in the Blattidae.^ 



ANAPLECTA Burmeister 

 1838. Anaplecta Burmeister, Handb. Ent., ii, abth. ii, pt. i, \). 494. 



Genotype: Anaplecta lateralis Burmeister, selected by Kirby, 

 1904.*^ 



The present genus, from the determined and undetermined 

 material at hand, is seen to be one of the largest of the Blattidae. 

 A great number of species apparently fall into the Lateralis Group, 

 including very small forms, uniform and dark in coloration, with 

 pronotum laterad and tegmina latero-proximad narrowly margined 

 with whitish or buffy. That this group may recjuire further divi- 

 sion is shown by the fact that some of the sj^ecies ha\e compara- 

 tively simply developed appendages of the male subgenital plate, 

 while in others these appendages are highly specialized. In addi- 

 tion, the wing development and venation shows some differentia- 

 tion in certain forms. The difficulty of group assignment is 

 increased by finding certain species of wholly different coloration, 

 such as A. asema and A. sordida here described, which in structural 

 features show nearest relationshij:) to forms ha\ing the character- 

 istic coloration of this group.
