40 entomological news. [February, 



In the Serricorn series some of the more conspicuous forms 

 only will be spoken of. The beautiful phosphorescent Elaterki, 

 Pyrophorus physoderus, was rather rare at the time of my visit, 

 though probably more abundant in proper season, Chrysobothris 

 octocola was moderately abundant on huisache* Collops vittaius 

 was common near the river and about the margins of the sloughs 

 (or resacas as they are locally termed), while a pair of C. baltea- 

 tus was seen on the great alkali flats between Brownsville and 

 the sea. Fence posts of native leguminous wood, were badly 

 infested by Sinoxylon sericans and beating tangled thickets was 

 certain to produce plenty of .S. dinoderoides which came no doubt 

 from dead twigs and branches. Amphicerus punctipennis was 

 found boring in the solid wood and occasionally just under the 

 bark of huisache, while Polycaon obliqims and plicatus were 

 attracted to light. Two specimens of Elasmocenis terminatas 

 were captured, one in my room, another by beating. Clems 

 abrtiptus was rare, C. quadrisignatus more common, the latter 

 chiefly about yuccas or under loose bark. Chariessa vestita, one 

 of our most beautiful insects, with violaceous upper surface and 

 sanguineous abdomen was twice seen running about on fence 

 posts in the hot sunshine. One Cregya vetusfa and several C. 

 oculata were taken by beating tangles of vines and bushes. A 

 great number of Rhipidandrus peninsularis (described from 

 Lower California by Dr. Horn), inhabited a polyporoid fungus, 

 boring through it like some species of Cis. 



Lamellicorns were few; Canthon l&vis was abundant along the 

 stage line, especially in sandy spots, but much less common at 

 Brownsville. C. ebenus occurred farther up the river at Laredo, 

 while a single C. simplex was found in July. Ch&ridium hisieroides 

 put in an appearance occasionally. Onthophagus cribricollis was 

 found in small numbers under dung in the pastures attached to 

 Fort Brown. Atcenius abditus and strigaius, Aphodius vittatus, 

 ruricola and lividus all came to hand at times, but nothing large 

 or fine was seen with the exception of Strategus julianus, a 

 single specimen of which flew across my path, to its own 

 destruction on the evening preceding my departure. 



Cerambycidae were tolerably numerous and several forms prove 

 to be new, either to science or to our fauna, while others are 



* A thorny leguminous tree, belonging to the group of Mimosas. It is abundant near 

 Brownsville.
