THE CANADIAN ENTOMOLOGIST 247 



narrowed anteriorly, the surface of interfrontalia finely striate on upper half 

 laterally; orbits narrow, distinctly separated from ocellar triangle posteriorly 

 their surfaces microscopically diagonally striate anteriorly; hairs on frons short 

 and sparse; third antennal segment three times as long as wide; cheek narrow, 

 without dense hairs or strong bristles. Thorax as in polita Say. Basal 

 abdominal sternite with some hairs on each side. Legs and wings as in polita. 

 Fringes of calyptra^ longer than usual, about six of the hairs at apex of the fold 

 setulose and longer than the calyptra?. 



Female. — Frons at least one-third of the head-width and less than 1.5 as 

 long as wide, not so distinctly striated as in male. Ovipositor as in polita Say. 



Length 4-4.5 mm. 



Type. — Male, allotype, and one male paratype, Santa Clara, Cal. (Baker) ; 

 one male, San Diego, Cal. (Harkins collection); one male, Palo Alto, Cal., 

 August 3. Type in collection of University of California. 



Lonchaea bakeri, sp. n. 



Female. — Glossy black, without distinct bluish tinge, the frons greenish 

 blue anteriorly. Face and cheeks with whitish pruinosity; frons shining upper, 

 orbits and ocellar triangle glossy; antennee brownish black. Legs black, tarsi 

 yellow, apical two segments darkened. Wings clear, veins yellow. Calyptrae 

 and their fringes white. 



Frons at vertex one-third of the head-width, not narrowed anteriorly, its 

 length about L5 of its width, surface microscopically striate on upper half 

 granulose anteriorly, with sparse hairs; upper orbits almost imperceptibly 

 striate; third antennal segment not twice as long as wide; face not carinate, 

 cheek with 3 or 4 strong, but not very long bristles on lower margin anteriorly. 

 A strong bristle on upper margin of mesopleura a little behind spiracle and 

 considerably cephalad of the vertical series at anterior margin of haired area; 

 scutellum without hairs between apical bristles. Ovipositor not broad, the 

 apical hairs very short. Hind femora w^ithout antero-ventral bristles; antero- 

 dorsal setulae on hind tibiae stronger than usual. Veins 3 and 4 very slightly 

 convergent apically. Fringes of calyptrae normal. 



Length 3 mm., exclusive of ovipositor. 



Type.- — Chinangega, Nicaragua (F. C. Baker). 



Named in honour of the collector. 



This species is closely allied to albiceps Malloch, having the same armature 

 of the mesopleura, and the same type of frons but without the transverse de- 

 pression, and the calyptrae white, and venation different. 



Type in collection of University of California. 



AN ADDITION TO BIBLIOGRAPHY ON AGRILUS (Coleop.). 

 Through an oversight on our part, a recent paper of Burke's was omitted 

 from the Agrihis bibliography, (Can. Ent., Sept., 1920, p. 204), and is given 

 below.
