388 FAMILY XI. — LYG^EID^:. 



of corium yellow; membrane brown with a vague pale spot near apex; 

 second and third antennals pale reddish-brown, first and fourth darker; 

 legs yellow, the apical third of front and hind femora darker. Anten- 

 nae with first joint slightly passing tip of tylus, second very slender, 

 longest; fourth stouter, slightly longer than third. Front lobe of pro- 

 notum impunctate, hind one with coarse sparse punctures. Scutellum 

 with a row of punctures each side and some scattered ones on disk. 

 Front femora armed beneath near apex with two large and several small 

 spines. Front tibiae of male slightly curved near base, armed with a 

 single small tooth. Other characters as given above. Length, 8 — 9.5 

 mm. (Fig. 83). 



Common in southern Indiana, much less so in the northern 

 counties ; occurs throughout the year. Hibernates both as 

 imago and nymph beneath various kinds of cover, especially 

 in dry loamy or sandy soil in open upland woods. Often occurs 

 beneath logs in company with Casnonia pennsylvanica L., a ground 

 beetle of somewhat similar form. They are the most bizarre 

 species of their respective groups and when their protective 

 cover is removed, unless benumbed with cold, they run hur- 

 riedly away, their slender necks and long swaying antennae giv- 

 ing them an odd appearance as they go. Both bug and beetle 

 are almost exclusively terrestrial in habit and are said to be 

 predaceous. Their long slender necks have perhaps been de- 

 veloped through the reaching into crevices in search of prey. 

 The known range of M. serripes extends from New England 

 west to Nebraska and Colorado and south and southwest to 

 Texas and Mexico. It has been recorded from "Florida" by 

 Uhler, and Van Duzee (1909, 171) mentions the taking of "a 

 small larva" at St. Petersburg. These records should probably 

 be referred to annulicomis described below. It is not known 

 from Canada and from the records is very scarce in northern 

 New York and Michigan. Uhler (1878, 388) mentions it as 

 "Occasionally common in stubble fields after the wheat and 

 oats have been removed ; sometimes also in the straw stored in 

 barns. It may be found hibernating in winter beneath stones, 

 logs and leaves or in stumps of trees behind loose bark." The 

 M. petiola Say (1832, 19) is a synonym.

Differs from serripes in having the elytra darker with pale costal 

 margin less distinct; joint 4 of antennae subequal in length to 3, broadly 

 annulate with pale yellow, the apical third and extreme base above 

 darker, joint 1 dark reddish-brown, 2 and 3 paler, the apical fourth of
