4 — Abdomen at most subpetiolate; thorax of 9 divided into more 

 than two parts (bodj^ at least the thorax, coarsely seulptnred).

Abdomen connected by a long, slender petiole; thorax (9) di- 

 vided into two distinct parts only; ^ unknown. 



4. ('IIVI'IIOTES BI. 



Tril)e II.— MYRMOSINI. 



Proposed for the genera Mijrutom and Mefliocn, and is character- 

 ized chiefly by the females jiossessing distinct ocelli. Ihit few 

 species have been described from America. 



Apex of abdo7Ben (J^ "I, unarmed: wings with three snbmargiual 

 cells; '' cubital nervure of hind w iiigs received by the submedian 

 cell at apex; thorax (J) coin posed apparently of two parts; 

 body rugose ( 9 ) Myrmosa Latr. 



A])ex of abdomen ( <? ) armed with a curved spine; two submargi- 



nal cells; cubital nervure of hind wings received considerably 



before the apex of submedian cell; thorax (9) divided into 



three parts; body smooth, shining and very ant-like. 



^rKTiiocA Ijatr. 



If the genus Thyiuius occurs in America as reported by Patton 

 (Ent. News, III, 104) another tril)e will have to be added to this 

 family. I doul)t, liowever, the existence of American representa- 

 tives. 



SCOLIIDJE. 



This family is sufficiently characterized by both sexes being 



winged to separate it from the iMutillida?. The North American 



representatives comprise three tribes," as follows: — 



Ej^es emargjnate; spur of fore tiliijc large, strongly curved, dilated, 



and truncate at end; intermediate tibiie w ith one spur; abdomen 



of ^ armed with three spines at apex SCOLIINI. 



Eyes entire ; spur of fore tarsi not much curved or dilated, either 

 pointed or bifurcate at end ; intenuediate tibijc witli one or two 

 spurs; abdomen of $ with but one spine at apex. 

 Sexes similar in form ; marginal cell broadened toward the 

 base (in our genera, the 9 '« have tlie marginal cell open at apex) ; 

 antenme short in both sexes TYPHllNl. 



■* This may ultimately prove but a division or sul)yenus of Jlfn/i7Ia. 



^ There are really four snbuiarj^inals, as the cubital ncr\ ure extends out to 

 the apex of wing.
