funicle usually five- jointed and club three- jointed, though in some 

 cases funicle is six-jointed and club two-jointed. Propodeum not or 

 scarcely longei| than . scutellum, not sharply declivous, usually 

 rugosely sculptured; with a more or less distinct median, longi- 

 tudinal depression. Sculpturing of head and dorsum of thorax either 

 reticulate and shining, rugulose punctate without umbilicate punc- 

 tures or rugulose with a few more or less indefinite umbilicate punc- 

 tures. 



Prof. C. R. Crosby, of Cornell University, kindly placed his speci- 

 mens and notes on H. phalaridis at the disposal of the writers. Pro- 

 fessor Crosby found that this species has two generations a year, 

 each generation confining itself to Phalaris arundinacea. The re- 

 maining species were reared from dried grasses collected in the field. 

 No further observations on their biology have thus far been made. 



Acknowledgment is made to Mr. A. B. Gahan of the United States 

 National Museum for his kindly criticism of the manuscript. 



Harmolita swezeyi, n. sp. 



(PI. XXXVI, figs. 2 and 5; pi. XXXVII, fig. 7.) 



Female. Length, 2.90 mm. Prescutum reticulately lineolate and without 

 broad, shallow impressions or umbilicate punctures. Pronotal spots large, 

 occupying about one-half of the anterior margin of prothorax, spots dull 

 yellowish. Sometimes entire thorax and propodeum brownish. Propodeum 

 without a distinct margined, median, longitudinal groove, though there is 

 usually a distince median longitudinal depression. Propodeum rugulose an- 

 teriorly and usually granulose in the remaining portion. Spiracular carinas 

 usually distinct but weak. Abdomen equal to or slightly longer than head and 

 thorax combined; conically pointed; second segment equals one-fourth length 

 of abdomen; remaining segments subequal, though five is longest and three 

 shortest. Legs in black specimens are black except at knees and tarsi, which 

 are luteous; in brownish specimens. the legs approach the color of the thorax, 

 knees and tarsi lighter. 



Antennae: Funicle five-jointed; first funicle plus ring joints longer than 

 pedical; all of funicle joints usually distinctly longer than broad; middle joint 

 of club apparently quadrate; scape and pedical yellowish. 



Species medium to small. Median line of face below insertion of antennae 

 without markings. 



Males. Unknown. 



This species will run to the couplet separating agrostidis and websteri in the 

 Phillips and Emery table of species, but may be readily distinguished from 

 either species by the yellowish scape and the longitudinal depression in the 

 propodeum. 



Type locality. Honolulu, Hawaii. 



Type. Cat. No. 25,471, U. S. N. M. 



Described from thirteen females reared from stems of Bermuda grass 

 {Cynodon dactylon), in Honolulu, Hawaii, by Mr. O. H. Swezey.
