586 FAMILY XIX. — REDUVIID^E. 



are deposited m clusters of eight or more on the surface of 

 leaves, and hatch in ten or twelve days. Uhler states that the 

 adults rove about in fields and near woods, ascending golden- 

 rod and other plants and seizing such insects as come within 

 their range. Hussey (1922a) reports it as extremely abundant 

 in August on dense growths of tall weeds everywhere in North 

 Dakota, and again "as the most abundant Reduviid in Mich- 

 igan, found in all grassy localities from late July till October." 



559 (806). Sinea sanguisuga Stal, 1862, 444. 



Elongate, slender. Dark reddish- to fuscous-brown; antennae red- 

 dish-brown, the incisures pale, the basal joint with a pale ring in front 

 of middle; femora and tibiae sometimes annulate or spotted with pale. 

 Spines of front lobe of head (fig. 145, b) gradually decreasing in length 

 from the base. Pronotum with front lobe armed with a number of small 

 tubercles and with a broad median impression beginning at its middle, 

 widening behind and ending at middle of hind lobe; humeral angles 

 obtusely triangular, projected somewhat backward; disk of hind lobe 

 convex, coarsely reticulate-punctate, its hind margin with a fringe of 

 small spines. Abdomen widened to apex of fourth segment, where it is 

 obtusely angulate and dentiform (fig. 145, d) , narrower in male than 

 female. Margins of connexivals finely serrate. Length, 10 — 13 mm. 



Ormond, Sanford, Moore Haven and Dunedin, Fla., scarce, 

 Nov. 16 — April 15. Occurs in late autumn on flowers of golden- 

 rod; in spring on weeds along the margins of ponds and road- 

 sides. Described from Mexico. Known in this country only 

 from Texas and Florida. Barber does not include it in his 

 Florida list, but Fracker mentions it from there without definite 

 locality. 



560 (807). Sinea spinipes (Herrich-Schaeffer), 1848, 82. 



Elongate, more robust than either sanguisuga or rileyi. Dark red- 

 dish-brown or fuscous; antennae reddish-brown, the basal joint with two 

 pale rings; median carina and apex of scutellum dull yellow; corium with 

 small scattered pale spots; connexivals 2, 3 and 6 each with a large pale 

 spot, 4 and 5 both in great part or wholly blackish; middle and hind 

 femora and tibiae annulate with paler. Spines of front portion of head 

 long and subequal. Pronotum with front lobe more convex than in 

 sanguisuga, otherwise as there; hind lobe wider, also less convex, its 

 reticulate punctures more shallow and spine or process of humeral angles 

 smaller, projecting outward. Apex of scutellum broadly rounded or sub- 

 truncate. Margins of connexivum entire or minutely tuberculate. Abdo- 

 men in male less widened to apex of fourth segment, the latter less acute 

 and without a backward projecting denticle as in sanguisuga. Length, 

 12—15 mm. 



Frequent in the southern half of Indiana, April 25 — Sept. 24,
