no. 2068. NEW SPECIES OF INSECTS— GAHAN. 159 



beyond the first smooth and polished; ovipositor exserted nearly the 

 length of the abdomen. 



Male. — Essentially like the female ; antennae 22-jointed in the type ; 

 abdomen spatulate. 



Type-locality. — Wellington, Kansas. 



Host. — Sarcopliaga, Icellyi. 



Type.— Cat. No. 18329, U.S.N.M. 



Five females and five males from the type locality reared by E. O. G. 

 Kelly and recorded under Webster No. 7398, Bureau of Entomology, 

 United States Department of Agriculture. 



In C. T. Brues's key to the species of this genus 1 this runs to section 

 7, but is apparently separable from all three species in that category 

 by the areolation of the propodeum and the different length of the 

 second flagellar joint. 



Superfamily CHALCIDOIDEA. 

 Family CALLIMOMIDAE. 



Subfamily MONODONTOMERINAE. 

 LIODONTOMERUS, new genus. 



Antennse 13-jointed, with two ring-joints; funicle 6-jointed; face 

 rather long and very slightly narrowed above; occipital foraminal 

 depression immargined; pronotum shorter than the mesonotum; 

 propodeum without carinae and also without spiracular sulci; mar- 

 ginal vein shorter than the submarginal, the stigmal shorter than the 

 postmarginal; front femorae not or only slightly swollen, posterior 

 femorae with very slight indications of teeth on the lower apical 

 margin or without any teeth; first dorsal abdominal segment incised 

 medially. 



Type of the genus. — Liodontomerus perplexus, new species. 



Plesiostigmodes, Ashmead Dimeromicrus , and Idiomacromerus, Craw- 

 ford have two ring-joints in the antennae. This new genus can be 

 separated from the first by the short pronotum and the unswollen 

 front femora, while from the others it differs in the immargined 

 occiput. 



LIODONTOMERUS PERPLEXUS, new species. 



Female. — Length, 1.6 to 1.8 mm. Antennae clavate; funicle joints 

 all broader than long and broadening slightly toward the club; club 

 broader than the funicle and about equal in length to the three last 

 funicle joints combined. Head and thorax closely punctate; the pro- 

 podeum less strongly sculptured than the rest of the thorax, only 

 faintly lineolated medially, the sculpture more evident laterally;
