114 Eighteenth Report State Entomologist of Minnesota — 1920 



black hairs, in length not eqnaling thickness of segment ; last two segments 

 mntilatcd ; fnsco-brownish, the basal segment more blackish. 



I'roiiotion : length .65 mm., width at base 1.25 mm., width at anterior angles 

 .8v3 mm. ; disk nearly flat, more convex where the callosities are indicated, gray- 

 ish testaceous, spotted and marked with fuscous, a row of black bristles on the 

 anterior submargin ; lateral margins nearly straight, beset with several bristles, 

 basal margin sulcate at middle and broadly curving to the basal angles ; pro- 

 pleura much reduced, coxal cleft distinct and cut well up under the lateral mar- 

 gin of disk, xyphus poorly developed. Mcsonotum smooth, median line appar- 

 ent as a fine impression which continues forward upon the pronotum ; wing- 

 pads reaching to posterior margin of the fourth visible abdominal segment, 

 ground color similar to pronotum but more closely spotted with fuscous, the 

 apical area, base, and the mesonotum largely clouded with fuscous ; lateral 

 margins of wing-pads beset with short stiff black bristles. 



Legs: black, apices of femora pale; hind tibiae biannulate with pale, a third 

 annulus indicated beneath the knee ; front and middle tibiae more broadly 

 pale, the three fuscous annulations much reduced, black on the knee ; tibial comb 

 fully developed and similar to that of the adult ; tarsi two-segmented, the second 

 segment three times the length of the first, blackish ; claws as in the adult, 

 arolia not distinguishable. 



Abdomen: testaceous, ten segments visible from the dorsal aspect, a sparsely 

 set row of black bristles transversely across the middle of each segment, each 

 bristle usually arising from a fuscous spot; the third tergite and half of the 

 fourth covered at middle by a conspicuous opaque blackish spot ; tergites 5-8 

 with a dark opaque spot at each side in the lateral submargin, placed nearest 

 the anterior margin of the tergite, the largest spot on the eighth tergite; spir- 

 acles situated on the ventral submargin and corresponding closely in position 

 with the dorsal spots just described. The anus is provided with an eversible 

 organ of sticky nature which enables the nymph, when disturbed and falling 

 from one limb to another, to attach itself to the first object it strikes until 

 such time as the feet can be brought into use again. 



Deraeocoris incertus new species 



Slightly larger than airivctttris, femora biannulate with pale on the apical 

 half ; base, middle, and apex of corium picoous ; eyes of male large, width of 

 vertex not equal to the dorsal width of an eye; segment II of male antennae 

 with fine short pubescence, devoid of exserted hairs. 



$. Length 5 mm. Head: width 1.06 mm., vertex .35 mm., lengtli .54 mm.; 

 carina much flattened, produced forward at the median line, a groove separating 

 it from the collum ; collum broadly exposed, black ; eyes large, dark brown, 

 nearly ovate when viewed from the side, mucli reducing the genal area ; black, 

 the pale markings very similar to those of iiubihts. carina, bordering front mar- 

 gin of eye below vertex, median line of fnmt below vertex and connecting be- 

 neath with juga, small spot below base of antenna, the median and a lateral 

 line on tylus, pale or white. Rostrum, length 1.85 mm., reaching upon the hind 

 coxae, piceous. 



.Inteiniae: segment 1, length .34 mm., Ijrownish black, i)aler on the apical 

 half; n, 1.65 mm., cylindrical, equal in thickness to segment T, constricted at
