back to Plecopteroid forebears rather than to Mantoid ances- 

 tors as HandHrsch considers to be the case. I place the 

 Coleoptera in the group Panplecoptera, next to the Dermap- 

 teron line of descent, thus differing from HandHrsch who 

 would derive the Coleoptera from the Protoblattoidea. There 

 are many other points of difference, especially in the grouping 

 and derivation of the higher insects ; but these will be taken 

 up under the discussion of the phylogeny of the other groups 

 of insects, in a series of papers dealing with each group in 

 detail.

 LiBELLULINAE. 



Libellula foliata (Kirby). Puriilha, 5500 feet, June 30, 1 ^, 

 "body orange brown, costal margins orange," 1 $, swampy road. 

 Guatemala City, July 1, 1 ^. 



These three specimens are younger than those described in 

 the Biologia volume and by Ris, in the Cat. Coll. Zool. Selys, 

 the males having the frons and vertex pale ochre, the female 

 pale greenish brown, both sexes with the labrum orange yel- 

 low. In the male from Guatemala City the genital lobe has a 

 posterior process or lobe similar to that figured for Brechmo- 

 rhoga postlobata (Proc. CaHfornia Acad. Sci. 3d Ser. Zool. I, 

 pi. xxv) but even more distinctly developed. I find no other 

 dififerentials correlated with the presence of this process so, 

 in spite of the precedent set by naming this Brechmorhoga, 

 do not consider this male worthy of a separate name, at least 

 until additional similar specimens come to hand.
