Material examined: Syntype GUATEMALA: ♀ Type BCA, Rhynch. II, Lasiochilus reuteri Ch., El Zumbador, 2500 ft., Ch. Sp. Figured. BMNH; ♂ Bark of Primavera log., Galveston, Tx, 1-V-1942. USNM; ♂ same data, N. Y. City, 7-V-1941 (slide-mounted). MACN; ♂ same data, 8-III-1938. USNM; HONDURAS: ♀ Under Primavera bark, N. Y. City, N4, 19-VIII-1939, L. reuteri Ch. , det H. G. Barber. USNM.
