A NEW GENUS AND SEVERAL NEW SPECIES OF CERAMBYCIDAE. 



(COL.) 



BY W. S. FISHER, U. S. Bureau of Entomology. 



In working over the coleoptera received from the field men of 

 the Branch of Forest Insects, U. S. Bureau of Entomology, dur- 

 ing the past year, the following apparently new species of Cer- 

 ambycidae were found. For one of these, a species from Ari- 

 zona, the larva of which lives in the branches of Canotia, it was 

 found necessary to erect a new genus. 



All types and specimens mentioned are deposited in the U. S. 

 National Museum at Washington. 



Anoplocurius, new genus. 



Maxillary and labial palpi about sub-equal in length; last joint oblong 

 sides nearly parallel, truncate at apex. Ligula membranous. Antennal 

 tubercles not prominent, contiguous. Head transverse; eyes large, coarsely 

 granulated, deeply emarginate. Antennae, of the male, one and two-thirds 

 times as long as the body; of female, about sub-equal in length to the body; 

 twelve-jointed. Prothorax longer than wide, cylindrical. Scutellum wider 

 than long, rounded posteriorly. Elytra distinctly wider than prothorax, 

 without eburneous spots; sides parallel; apices separately rounded. Pros- 

 ternum very narrow between the coxae. Anterior coxal cavities strongly 

 angulated, open behind. Intermediate coxal cavities angulated and closed 

 externally. Femora moderately clavate, slightly flattened, not dentate be- 

 neath. Tibiae slender, not carinate longitudinally, with two equal spines 

 at the apex. First joint of posterior tarsi as long as the two following joints 

 united. Body narrow, linear, somewhat flattened, first abdominal segment 

 as long as the two following segments united. 



Genotype. Anoplocurius canotiae Fisher. 



The species for which this genus is founded has the general 

 aspect of the genus Citrius and some of the small species of Ela- 

 phidion. From the former it is easily distinguished by not having 

 a tooth on the femur, and from both of these genera by having 

 a twelve-jointed antennae. 



This new genus belongs to LeConte and Horn's tribe Ceramby- 

 cini, and to Lacordaire's group Callidiopsid.es, but it seems to be 

 one of the new discoveries which do not fit well in any of the 

 proposed groups.
