characters are hardly sufficient for the erection of a separate genus, 
particularly when the other genera placed in this family are so distinct 
from the genus Lyctus in the broad sense. Therefore, I prefer to keep 
the generic name Lyctus in the old sense to include Trogoxylon , at least 
until more comprehensive work is done and it is demonstrated that other 
characters, such as those of the larvae and male genitalia, show that 
further division of Lyctus is necessary. 
The following information should help in the recognition of the three 
species mentioned above and summarizes their distribution. The host 
data are from specimens in the U.S. National Museum collection. 
Lyctus prostomoides Gorham 
Lyctus prostomoides Gorham (J3, p. 212) 
Type locality : El Tumbador, Guatemala. 
Size 2.5-5 mm. Color reddish-brown. Head with a prominent 
double tubercle over the base of the antennae; thorax widest in front, 
lateral margins nearly straight, anterior and posterior angles acute, 
punctures moderately large, dense, deeper than those of elytra; outer 
apical angles of anterior tibiae moderately produced; elytral pubescence 
confused, moderately long and dense, recumbent, fine, yellow in color, 
punctures confused, shallow, moderately dense. 
This species will key to "Section a2" in Kraus's key (4), but will fit 
neither alternative in that couplet because the pronotum is broader than 
long and the pubescence is fine and not bristling and the prosternum is 
not distinctly punctate throughout. 
Hosts: Lacquered tray, wooden crate, dry wood, bamboo, carved 
wood, basket, furniture, stem of Sambucus sp., and dried herbs. 
Distribution and interceptions : Panama: San Lorenzo (Champion); 
Guatemala: San Geronimo, Purula, El Tumbador (Champion); ?Nicaragua: 
Chontales (Janson); Mexico: Cordoba (Knab), Jalisco (Diquet), Guanajuato 
(Salle), Cuernavaca (via Chicago, 111.), Guadalajara (via Nogales, Ariz.), 
"Mexico" (via Brooklyn, N. Y.), "Mexico" (via New York, N.Y.), 
"Mexico" (via Pittsburgh, Pa.), "Reared from elephant carved from 
soft African wood purchased from London dealer in Persian goods" 
(via Rochester, N.Y.). 
Lyctus impressa Comolii 
/Tyctusj7 /Tmpressa]?7 Comolii (J_, p. 40). (Publication not seen.) 
Type locality: presumably Novocomi (Italy?)
