102 LE CONTE.— LONGICORN COLEOPTERA 



The present genus confirms the suspicion that I expressed, that genera with 

 11-jointed antennse would enter the fourth group. The form approaches somewhat 

 the TrachyderidsB. 



1 . P. viTTATUS. — Niger, grosse punctatus, pube grisea longiore erecta vestitus, thorace vix transverse, ad 

 apicem angustato, convexo, basi bisinuato, lateribus rotundatis, callo parvo nitido ad medium, maculaque 

 utrinque basali aureo-pubescente; eljtris nigris, lineis utrinque duabus laevibus elevatis flavis, pedibus 

 rufis, tarsis nigris. Long. '55. 



One specimen, San Diego, Cahfornia. The scutellum is covered with dense yellow 

 hair, the exterior vitta of the elytra is abbreviated at each end ; the anterior portion 

 of the epipleurae is yellow. 



CROSSIDIUS. 

 Antennae ll-articulataj. 



Mandibulse apice late truncatse, paulo emarginatae. 

 Thorax rotundatus, convexus, dorso vix callosus, lateribus subangulatus. 

 Mesosternum planum, antice non subito declive. 

 Elytra apice vix truncata, baud arraata. 

 Corpus dense pubescens. 



The males have the antennse but little longer than the body ; the form is short and 

 stout, like Asemum ; but the insects seem to live on flowers. 

 1. T. TESTACEUS. — Testaceus, dense flavo-pubescens, thorace grossius punctato, transverso, utrinque truncato, 



lateribus subangulato, dorso obsolete tricalloso, elytris dense punctatis, grossius versus basin, lineis 



utrinque duabus obsoletis laevibus elevatis. Long. -65. 



San Diego and Colorado River, on Baccharis.

3. E. Haldemani. — Testacea densius flavo-pubescens, thorace subtransverso, fere quadrato antice baud 

 angustato, lateribus breviter armatis, dorso grosse punctato, callo utrinque ante medium minus distincto 

 alteroque ante basin : elytris sat punctatis, callis utrinque 2 basalibus parvis discretis, alterisque ad 

 medium approximatis, intcriore minore. Long. '95. 



Fort Gates, Texas. Lt. Haldeman. The thorax more square than in E. 4-geminata, 

 with larger and more distinct punctures; the basal callosities of the elytra are 

 separate, the tip is truncate, but the outer spine is scarcely visible ; the inner one 

 distinct.

6. Elaphidion incertum. The reference to the Ent. Mag. is wrong; these species are 



described by Newman in the Entomologist.
