PREDACEOUS HEMIPTERA. 397 



end of the abdomen is a larger horizontal spot, which covers 

 the anal segments and often connects the two posterior 

 lateral spots. The under surface of the body is yellowish 

 red, darkest on the abdominal segments. The lateral row 

 of semi-elliptical spots, similar to those upon the upper sur- 

 face, extends around the entire margin of the abdomen. 

 Beak stout, four-jointed. Both beak and legs are of a dark 

 copper color. Tarsi two-jointed ; claws simple, two in num- 

 ber, light brown, each with a darker pulvillus ; legs sparsely 

 clothed with pale-brown hairs. 



The first molt takes place in about four days from the 

 time of hatching, and is accompanied by a marked increase 

 in size. 



Second Stage. The second stage of this insect is repre- 

 sented on Plate 61, Fig. 3. Length, 3.5 mm. ; body a little 

 longer in proportion to the width than in the first stage ; 

 head quadrangular, with two faint sulci, extending backward 

 from the anterior margin for about one-third of the length 

 of the head. Eyes prominent. Basal joint of antennae short 

 and stout ; second joint cylindrical, truncate at the end, twice 

 as long as the basal joint ; third joint slightly longer than 

 basal joint, and somewhat rounded at the outer end ; fourth 

 joint appressed at each end, and of nearly the same length 

 as the second joint. The thorax is slightly serrate around 

 the outer margin, and its outer angles project by the base 

 of the head for a short distance. The color of the head and 

 thorax is dark seal brown, varying to a pitchy black. Ab- 

 donien of the same color as in the preceding stage, but 

 with four horizontal spots instead of three, the second and 

 third spots being much larger than the first and fourth. 

 Lateral spots as in the first stage. The under surface of 

 the head and thorax is marked with dark brown, that of the 

 abdomen being the same color as in the preceding stage. 

 Beak and legs dark brown, lighter on the tarsi. 



The second molt, with an accompanying increase in size, 

 takes place from eight to ten days after the first molt. 



Third Stage. The third stage is represented by Plate 

 61, Fig. 6. Length of body, 6 mm. ; form somewhat ovate, 

 narrowest in front. The head is narrowed from that of the
