NOTE ON THE CORUCO, A HEMIPTEROUS INSECT WHICH 

 INFESTS POULTRY IN SOUTHERN NEW MEXICO. 



By C. H. TYLER TOWNSEND. 



There exists in southern New Mexico a Cimicid, known by 

 the Mexican name of Coruco, which is an unmitigated pest of 

 poultry in this region. When the insect once gains access to a 

 hen-house, it soon swarms in great numbers, infesting the in 

 mates and roosts, and covering the eggs with its excrementa, 

 which show as black specks. It is a very difficult pest to ex 

 terminate, and has frequently been known to spread from roosts 

 to dwelling-houses, where it proves more formidable than the 

 bedbug. This insect also exists in western Texas. 



In a paper published in La Naturaleza (zd series, vol. ii, 

 1892, pi. viii, 8 figs.), Dr. Alfredo Duges has described and care 

 fully figured a similar species, under the name of Acanthia 

 tnodora, which infests poultry in the region about Guanajuato, 

 Mexico. 



Our species seems to be the same as A. inodora A. Duges. 

 The following is a brief description of the nymph, made from 

 specimens taken from roosts in a hen-house in Las Cruses on 

 May 22, 1891. It is designed to show the peculiarities of the 

 nymph as compared with the description and figures of the 

 adult given by Duges, which correspond quite well with our 

 specimens. 



Nymph. Length, i| to 2^ mm.; greatest width, i to i| mm. Pale 

 whitish in color during life; changed by immersion in alcohol to a brown 

 ish color, legs pale yellowish with a brownish tinge, and eyes brown.
