DESCRIPTIONS OP NEW SPECIES. 8t 



PRIOXOCYPHON REDT. 



318. P. limliatiis. Late ovatus, rufo-testaceus, flavo-pubescens, tho- 

 race punctulato, elytris fortius minus dense punctatis, piceis limbo 

 omni rufo-testaceo ; antennis subserratig fuscis, articulo lino flavo, 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 i in the form of the first joint of the antennae, 

 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. 



HE LODES 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 punctate, lateribus reflexis 

 margine tenui diaphano, elytris sat dense punctatis ; coxis et femoribus 

 flavis, his 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. 



320. H. explanata. Longiuscula, oblongo-ovalis, fusco-testacea, 

 pube brevi sericans, thorace brevi, dense punctulato, fusco, lateribus 

 valde rotundatis late explanatis et reflexis, elytris confertim subtilius 

 punctatis, sutura infuscata, stria suturali obsoleta antice abbreviata ; 

 antennis articulis 2 et 3 aequalibus, 4to conjunctis paulo breviore. 

 Long. -20. 



One specimen, Ottawa, Canada ; Mr. B. Billings. A species 

 belonging to Microcara Thomson, which is received as a genus 

 by Kiensenwetter, 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 H. limda, but differs by the 

 larger size of the 2d joint of the antennae, 

 g* December, 1865.
