152 DESCRIPTIONS OF NEW SPECIES. 



HALLOMEtflJS PANZEK. 



446. H. punctlllatus. Subtus fusco-testaceus, supra fuscus, sub- 

 tiliter confertissime punctulatus, pubescens, tliorace lateribus vittaque 

 dorsali fusco-testaceo ; elytris striis 4 vel 5 internis fere obsoletis, basi 

 late indeterminate fusco-testaceis. Long. -22. 



One specimen, Quebec, Canacla; Mr. Couper. Of the same 

 form as H. scapularis Mels., but at once distinguished by the 

 much finer and denser punctuation, and by the obsolete striae of 

 the elytra, which are wanting in that species. 



This species agrees with the description of H. basalis Maun., 

 Bull. Mosc. 1853, 267, except that the elytra are feebly striate. 



Types of H. scapularis Mels., and Mycetochares ruficornis 

 Mels., for which I am indebted to the author, show no differences: 

 H. luridus is founded on paler colored specimens, which, as sur- 

 mised by Mr. Haldeman, on comparison, have proved to belong 

 to the same species. 



4-17. H. <lel>ilis. Testaceus, subtilius dense punctulatus, pubescens, 

 capite fusco, elytris sutura anguste, lateribusque ad medium paulo infus- 

 catis. Long. -]3. 



Two specimens, Illinois; Mr. B. D. Walsh. Differs from H. 

 scapularis by its much smaller size, and more dense and some- 

 what finer punctuation. Except in the characters mentioned the 

 two species here described agree with H. scapularis. 



EUSTROPHUS LEG. 



448. Ell. con fin is. Ovalis convexus, utrinque sequaliter rotundatim 

 attenuatus, niger, dense subtiliter griseo-pubescens, tliorace confertiin 

 subtiliter punctate, basi trisiuuata, tenuiter marginata, lobo medio late 

 rotundato ; elytris punctis approximatis striatim digestis, interstitiis 

 dense punctulatis ; subtus helvo-pubesceus, tarsis piceis, antennarum 

 basi et apice palpisque piceo-rufis. Long. -24 -30. 



Canada, Lake Superior, and Western States. Differs from Eu. 

 bicolor by the body not being more attenuated behind, by the 

 thorax being much more punctured, by the punctures of the elytral 

 striae being smaller, and by the legs being black ; it differs also 

 from Eu. indistinctus by the same characters, except that of 

 form, which is nearly the same in the two species. 



MICROSCAPHA LEG. 



Corpus parvum ovale, supra arcuatum, convexum, postice s.ubito magis 

 acute angustatum. Caput parvum deflexum, sutura frontali distincta ;
