DESCRIPTIONS OF NEW SPECIES. 87 



PRIONOCYPHOW Redt. 



3l§. P. limbatus. Late ovatus, rufo-testaceus, flavo-pubescens, tho- 

 race punctulato, elytris fortius minus dense punctatis, piceis limbo 

 omni rufo-testaceo ; antennis subserratis fuscis, articulo lino ilavo, apice 

 haud producto. Long. -15 — *21. 



Middle States. Agrees in coloration with P. discoideus, but 

 the dark spot of the elytra in the male is so large that only a 

 narrow basal sutural lateral and apical margin remains yellow: 

 in the female the spot is not well defined in front. The punctures 

 of the elytra are larger and less dense ; but the best distinguish- 

 ing character is in the form of the first joint of the antennas, 

 which in P. discoideus is prolonged and nearly acute at the tip, 

 but broadly rounded in the present species. 



The male (as in the European species) is only distinguished 

 from the female by the antennae being longer and stouter : no 

 vestige of the double series of slender appendages observed in 

 the male of P. discoideus is seen. 



HELODES Latr. 



319. H. apicalis. Elongata, subtus nigro-picea, supra lutea, pubes- 

 cens, capite, macula thoracis apicali, elytrisque apice nigris, fronte et 

 ore luteis ; thorace semicirculari subtiliter punctato, lateribus refli 

 margine tenui diapbano, elytris sat dense punctatis ; coxis et fernoril>u> 

 flavis, bis supra fuscis ; antennarum articulis 3 primis subtus flavis. 

 Long. *16. 

 One specimen; San Francisco, California. Of the same form 



as the European H. pallida. The 3d joint of the antennae is 



scarcely half as large as the 2d. 



32©. H. explanata. Longiuscula, oblongo-ovalis, fusco-tt^ - 

 pube brevi sericans, tborace brevi, dense punctulato, fnsoo, lateribus 

 valde rotundatis late explanatis et reflexis, elytris oonfertim Bubtilina 

 punctatis, sutura infuscata, stria suturali obsoleta antioe abbreviata ; 

 antennis articulis 2 et 3 a;qualibus, 4to conjunctis paulo breviore. 

 Long. -20. 



One specimen, Ottawa, Canada; Mr. B. Billings. -\ Bp 

 belonging to Microcara Thomson, which is received as a genus 

 by Kicnsenwetter, but only as a division of Helodes by DuvaL 

 The opinion of the latter seems to me more natural. 



It is related to the European //. livida, bul differs by the 

 larger size of the 2d joint of tin 1 antenna'.
