77^ CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 



This species is occasionally met with in sweeping vegetation, 



especially trees. The form described here agrees with Uhler's 



description and type, but it is not the serieventris of some authors. 



The black spot of the corium appears to be a constant feature, and, 



together with the rather blunt pronotal angles and short ventral 



spine will serve to distinguish this from the other members of the 



genus. In size it is often exceeded by females of modestus.

Zicrona Amyot and Serville. 



Tylus and juga of equal length ; lateral margins of pronotum 

 entire, not carinate; scutellum rather large, broadly rounded at 

 apex, the frena reaching to about the middle; bucculae small; 

 femora unarmed ; tibiae not sulcate above, flattened toward apex ; 

 abdomen unarmed at base, the third, fourth, and fifth segments 

 depressed along median line ; sericeous patches lacking. A single 

 species is known. 

 Z. caerulea (Linnaeus). 



Syst. Nat., Edn. 10, i, 445, 1758. 



Iridescent greenish blue ; antennae black. Length 6-7 mm. 



This beautiful species has a very wide distribution, being found 

 throughout Europe and Asia, in Japan, the Dutch East Indies, and 

 North America. Within New England it has been met with very 

 rarely, on the summit of Mount Washington and on the coast of 

 Maine, but in the western states it is of common occurrence. 



Adventitious specimens have been taken in Connecticut in boxes 

 of nursery stock imported from France. 



Family CYDNIDAE. 



By Howard Madison Parshley, Sc.D. 



This family comprises a moderate number of species small or 

 medium in size and usualty black in color, including those with the 

 scutellum large and convex, formerly known as Corimelaenidae, as 

 well as some with the scutellum smaller and flat, the Cydnids 

 proper or burrowing bugs. Many of the species are retiring in 

 habits, living obscurely in the ground, under stones, and in decay- 

 ing wood, others frequent the leaves of plants, occasionally becom- 

 ing injurious, and a few are found in more or less close association 

 with ants. The tibiae are strongly spinose; antennae generally 

 inserted near the base of the head and distant from the lateral 

 margin ; propleura convex in front, depressed behind ; abdomen 

 with five ventral segments visible in addition to the external geni- 

 talia, the true first being hidden except for its narrow posterior 

 margin.
