SUBFAMILY IV. — REDUVIINiE. 555 



Leconte's types were from Georgia, and following his orig- 

 inal description he says : "This insect inflicts a most painful 

 wound. It is remarkable also for sucking the blood of mam- 

 mals, particularly of children. I have known its bite to be fol- 

 lowed by very serious consequences, the patient not recovering 

 from its effects for nearly a year." Marlatt (1896, 38) has 

 given an excellent account of its life history and habits. He 

 states that : 



"It feeds on bed-bugs, especially those already charged with human 

 blood, and has a 'buggy' odor, even more intense than that of the bed- 

 bug. In country places, especially in the lower Mississippi Valley, it is 

 often found in bed rooms and its bite is very severe and painful, result- 

 ing in much more pronounced swelling and inflammation than in the 

 case of the bed-bug. It is a night flyer and is attracted into open win- 

 dows by light. It conceals itself during the day under any loose object, 

 often leaving beds which it may have frequented during the night." 



530 (736). Triatoma heidemanni Neiva, 1911a, No. 44. 



Form and size of sanguisuga. General color dark reddish-brown; 

 scutellum, hind lobe of head and front one of pronotum, piceous-black; 

 side margins of hind lobe of pronotum, costal margin and basal fourth 

 or less of corium and a spot near apex of latter, dull yellow; membrane 

 pale to dark brown, a triangular spot in front of its base paler; apical 

 third of each connexival both above and beneath, dull reddish-yellow. 

 Joints 1 and 2 of antennas brown, 2 thickly beset with long appressed 

 bristly hairs ; 3 and 4 straw- yellow, beset with numerous long, slender 

 flying hairs; 2 but slightly longer than either 3 or 4, which are sub- 

 equal in length. Pronotum with disk of hind lobe much smoother and 

 carina? lower and more obtuse than in sanguisuga. Third joint of beak 

 much shorter and more obtuse, and spine of scutellum shorter and less 

 cylindrical than in sanguisuga. Length, 18 — 22 mm. 



Lake Landing, Hyde County, N. Car., Aug. 25 (Brimley). 

 Riley Co., Kan., April 6 (Barber) . Ranges from Maryland west 

 to southern Illinois and Oklahoma and southwest to Florida 

 and Texas. This is the species treated by Stal, Fracker and 

 most American authors as variegata Drury, that name belong- 

 ing to an Antiguan species not represented in this country. 

 Some of the American records of variegata belong to sanguisuga 

 and the southwestern ones probably to the T. neotomce and 

 occulta Neiva, described from Arizona and Texas. The only 

 probable Florida record of heidemanni is that of Uhler (1878, 

 428) as variegata without definite station. No mention of its 

 habits can be found. Easily distinguished from sanguisuga by 

 the hairy beak.
