24 INSECUTOR INSCITI^ MENSTRUUS 



Both the above discussed genera could be referred with about 

 equal reason to either the subfamily Copiphorinae, where Decti- 

 nominia was originally included, or Agroecinae, where Uchuca 

 has been placed. The fastigium of the vertex varies from a 

 little broader than the basal segment of the antenna to a little 

 narrower and in some specimens there is a slight dorsal im- 

 pressed line. The coloration and the short falcate ovipositor 

 rather favor their inclusion in Agroecinse and Dectinomima is 

 therefore here referred to that subfamily. It is somewhat 

 doubtful, however, if Agroecinse should be considered as of 

 subfamily rank as there seems to be no very constant character 

 to separate it from Copiphorinae. The character used in this 

 connection, the fastigium of the vertex being broader than the 

 basal segment of the antenna in Copiphorinae and no broader 

 in Agroecinae, is a slight one upon which to base subfamilies, 

 being unimportant and not very constant. But a combination 

 of characters such as general color, shape of ovipositor, etc., 

 refers most species to one or the other of these two groups with 

 considerable certainty. 



The three known species of Dectinomima may be separated 

 as follows : 



Fastigium of the vertex fully as broad as the basal segment of the 

 antennae; pronotal disk semicircularly rounded posteriorly (PI. II, 

 fig. 15, a) ; abdomen wholly black, the sides no darker than the dor- 

 sum jenningsi Caud. 



Fastigium of the vertex scarcely as broad as the basal segment of 

 the antenna; pronotal disk less rounded posteriorly; abdomen 



with the sides noticeably darker than the dorsum 2 



Pronotal disk distinctly rounded posteriorly (PI. II, fig. 1.5, h) ; a 



stouter and darker species peruviana, n. sp. 



Pronotal disk subtruncate posteriorly (PI. II, fig. 15, c) ; a less robust 

 and lighter colored species pallida, n. sp. 



Subfamily PSEUDOPHYLLIN^ 



There appears to be much confusion in this entire subfamily 

 and determinations by well-qualified specialists are often made 

 with a query. The generic relationships are not well worked 

 out and a general revision of the group is needed. Brunner 

 laid too much stress on minor characters, such as certain spines
