CRYPTOHELCOSTIZUS ORNATUS, new species 



This species also is very closely related to alamedenms, but may 

 be distinguished from that and from both the other species by its 

 highly ornamented head and thorax. In the following description 

 only those characters are given by which it differs from alamsdenms. 



Femah. — Length 11 mm., antenna 7.5 mm., ovipositor sheath 3 mm. 



Face mostly polished and sparsely pmictate, combined length of 

 face and clypens fully as long as width of face (distinctly shorter in 

 alumedensh) ; interfoveal line hardly longer than foveo-ocular line 

 (much longer in alamedensh) ; temples convex; ocellocular line much 

 shorter than postocellar line and a little longer than diameter of an 

 ocellus (in alamedenHu the postocellar and ocellocular lines are nearly 

 equal and nearly twice as long as the diameter of an ocellus) ; apical 

 joint of antenna tapering slightly (cylindrical in alainedensis) ; first 

 tergite a little more slender than in almnedenMS, with spiracles 

 slightly beyond middle; spiracles of second tergite at middle (dis- 

 tinctly before middle in alamedensU) ; sheath of ovipositor much 

 less than half as long as body. 



White markings of head and thorax much larger than in odwrne- 

 deihsis; orbital ring very broad and only narrowly interrupted on ver- 

 tex and malar space, contiguous Avith eye posteriorly and broadening 

 below to embrace nearly entire width of cheek; antennal annulus on 

 flagellar joints 7-9 ; collar and both upper and lower margins of pro- 

 notum broadly white, as are also the subalar tubercle, tegulae, apex 

 of scutellum, postscutellum, two large lateral spots and a small me- 

 dian spot at apex of propodeum, upper surfaces of all coxae largely, 

 and basal joints of front and middle trochanters except dorsally 

 (coxae and basal trochanteral joints otherwise black) ; first tergite 

 black, with apex broadly ferruginous and with the extreme apex 

 medially yellow. 



Ho>st. — Chrysohoth't'is deserta Horn in desert holly.

APOTEMNUS, new genus 



The proper position for this unusual genus, whether in the Phy- 

 gadeuonini or in the Hemitelini, is very doubtful. In none of the 

 keys to the Phygadeuonini will it run to any genus that evenly re- 

 motely resembles it in general form. Because of its slender anten- 

 nae, hairy face, and distinct notaulices it runs best to Panargyrops 

 Foerster, but beyond these characters and its bidenticulate clypeus it 

 has little in common with that genus. In the keys of Foerster and 

 Ashmead to the Hemitelini it runs directly to Isadelphus Foerster,
