Habitat: United States, Mexico and Central America. Type, 

 Mus. Holm. 



The table will enable the student to separate this species from the 

 other members of the genus. Some difificulty may be experienced in 

 separating it from spinipes as the differences here are but relative. The 

 abdomens of the males are usually sharply angulated on the fourth 

 segment, sometimes also on the fifth. The specimens in the National 

 Museum are from Texas.

Length, 12-15 '^'"- First pair of anteocular spines seldom twice as long as the 

 third. Thorax as in sanguisitga. Abdomen entire. The fourth and basal half of 

 segments five and six of the abdomen generally conspicuously darker than the rest of 

 the body, usually more constant in the females. 



Habitat : United States, Mexico and South America ? 



This species was described and figured from South America by 

 Herrich-Schaeffer in 1848, but it has never since been reported from 

 that locality. In 1872 Stal gave its habitat as Mexico. It occurs all 

 over the southern and central parts of the United States. Its closest 

 ally is sanguisuga and the differences . enumerated in the table will 

 usually separate them. The range of spinipes seems to extend farther 

 north than does that oi sanguisuga, the latter species generally occurring 

 only in the extreme southern states. The distinct black band across 

 the abdomen especially in the females, will usually serve to separate it 

 from its allies, though this is sometimes seen, to a lesser extent in 

 sanguisuga and especially in defecta. The long anteocular spines at 

 once separated it from the latter species.

Length, 9.5-12 mm. Head with large tubercles or short blunt spines before the 

 eyes instead of well developed spines. Anterior prothoracic lobe armed with tubercles, 

 posterior lobe unarmed, convex on the disk. A pale fascia at the lateral extremity of 

 each segment of the abdomen, which is entire and with the margins well rounded, not 

 at all angulated at the sides in either sex. Membrane of the hemelytra with a longi- 

 tudinal dusky mark extending to the tip, rarely obsolete or not easily seen. 



Habitat : United States. Type, Coll. Montandon.
