714 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [BuU. 



Massachusetts, Rhode Island and at Yaphank, Long Island, there 

 is little doubt of its occurrence within the state. 



Ortholomus Stal. 



O. scolopax (Say), (longiceps Stal.) 



Het. New Harm., 15, 1832. 



Testaceous, with the head and pronotum, for the most part, 

 mottling of hemelytra and legs ferrugineous, with the apex of 

 the corium rufescent. The membrane, either clear or in part 

 milky white with a fuliginous streak down the middle. The apex 

 of the basal segment of the antenna extends to apex of head, with 

 the second and third segments subequal. The rostrum reaches 

 upon the second ventral segment of the abdomen. Length 5-6 mm. 



Often confused with Belonochilus numenius Say, which is, how- 

 ever, much paler with a longer head and rostrum, the latter 

 extended nearly to tip of abdomen.

The members of this genus can easily be distinguished from the 

 preceding by the fact that the costal margin of the corium is 

 straight only for a short distance at base, the corium being wider 

 than the abdomen, so that no part of the connexivum is visible. 

 The eyes are very nearly or quite in contact with the anterior 

 angles of the pronotum. 



Key to Species. 



1. Costal margins of corium at base straight for a distance nearly 



equal to length of scutellum thence gradually expanded. Bucculae 



reaching beyond middle of gular region. Smaller species 2 



Costal margins of corium straight at base for a distance less than 

 half of scutellum, then abruptly expanded. Bucculae less than^ 

 half the length of gular region of head. Larger species californicus 



2. Basal segment of antenna short, scarcely exceeding apex of head, 



little more than one-third the length of second. Antenniferous 

 tubercles shorter. Eyes less bulging ; width across eyes less than 

 diameter of posterior margin of pronotum. Bucculae gradually 

 evanescent posteriorly, not reaching base of head. Corium less^ 



expanded posteriorly encae 



Basal segment of antenna longer, usually exceeding apex of head 

 by nearly half its length, nearly one-half as long as second. 

 Antenniferous tubercles more prominent. Eyes more bulging; 

 width across eyes about the diameter of posterior margin of pro- 

 notum. Bucculae extended to or very nearly to base of head, 

 more elevated throughout, not gradually disappearing posteriorly
