following note from Psyche, vol. v, page 405, August to October, 1890, 

 as referring probably to the same species : 



Early last August a green cockroach of considerable size, Panchlora nivea (Linn.), 

 was found alive with a multitude of young ones just hatched in the bath-room of a 

 bouse on Lafayette street, Salem, Massachusetts, and sent to Mr. S. H. Scudder for 

 determination by Prof. E. S. Morse. It is a native of Cuba and Central America. It 

 is curious that Mr. Scudder has also in his collection a specimen marked as found 

 flying in a store in Boston, 26 December, lb78, on the authority of the late Dr. Sam- 

 uel Kneelaud.

No mention is made in the above item of the viviparity of the roach, 

 but from the wording and from the fact that no egg-case is mentioned 

 it is altogether likely that the facts were similar to those given by Dr. 

 Gissler in the case which he observed. As stated before the Entomo- 

 logical Society: "The significance of this exceptional fact is that the 

 extrusion of the eggs in a compact ootheca is supposed to be one of the 

 distinguishing features of the family Blattidce, and such cases serve to 

 show how difficult it is to lay down any rule in reference to the charac- 

 teristics of any group that may not involve exceptions. So far as other 

 family characteristics are concerned there is nothing peculiar in this 

 species of Panchlora. It is a rather soft-bodied species, with ample 

 wings. I would call attention, however, to the fact that the young have 

 either lost or never had the green color of the parent. They are pale- 

 brownish, and are further peculiar in that the body broadens posteri- 

 orly, the abdominal joints being strongly contracted and telescoped 

 into each other, the eighth and ninth so strongly drawn into the sev- 

 enth as to give the abdomen an unnatural, foreshortened, truncated 

 appearance. Whether this feature is due to the alcohol or is normal 

 it is impossible to say; but there is no evidence of any other portion of 

 the body having shrunken or contracted on account of the preservative 

 liquid."
