Lestodiplosis satiata new species. 



This species is an extreme form, placed here, though the prolonga- 

 tion of several dorsal loops of the circumfili suggest a relationship to 

 Aphidoletes. The male was collected August 28, 1917, by Mr. 

 Howard Notman at Keene Valley, N. Y. It falls in the key near L. 

 triangularis Felt and L. asclepice Felt, from both of which it is readily 

 distinguished by characters given below. 



Male. — Length 1 mm. Antenna; more than twice the length of the body, 

 thickly haired, mostly pale yellowish, the two basal antennal segments and 

 most of the basal enlargements of the others somewhat fuscous ; 14 segments, 

 the fifth having stems each with a length 2]^ times its diameter; one or more 

 dorsal loops of the circumfili greatly produced and with a length fully twice 

 that of the normal loops; terminal segments produced, the basal portion of the 

 stem with a length about six times its diameter, the distal enlargement sub- 

 cylindrical, somewhat expanded distally and apically forming an obtuse cone. 

 Palpi : first segment irregular, the second about twice the length of the first, 

 the third a little longer than the second, more slender, the fourth a little longer 

 than the third. Mesonotum dark brown. Scutellum and postscutellum yellow- 

 ish brown. Abdomen mostly dark brown. Wings rather indistinctly spotted 

 with fuscous, iridescent spots. Halteres whitish transparent. Coxae and legs 

 mostly dark brown, the distal portion of femora, the distal and basal thirds 

 of tibiae, the distal half of the second tarsal segment and the third, fourth, and 

 fifth tarsal segments mostly yellowish. Claws rather long, slender, slightly 

 curved, the pulvilli nearly as long as the claws. Genitalia : basal lobe of the 

 somewhat slender basal clasp segment unusually small, dorsal plate short, 

 deeply and narrowly emarginate, the lobes broad, irregularly rounded and 

 setose ; dorsal plate moderately long, broad, broadly rounded and thickly 

 setose apically. Type Cecid. 1775. 



NOTES AND NEW SPECIES OF BEMBIDIUM. 



By Howard Notman. 

 Brooklyn, N. Y. 



In a paper on some coleoptera collected at Cochrane, Ontario 

 (Jour. N. Y. Ent. Soc, Vol. XXVII, p. 92), the writer described a 

 species of Bembidium to which he gave the name B. lengi. A further 

 study of the descriptions of related species and the collection of more 

 material indicate some points of interest worthy of mention.
