Two species occur in our fauna. 



Piceous, elytra with an oblique testaceous stripe from the humeri. 



biplagiatus Dej. 

 Testaceous, head piceous fusciceps Lee. 



A. biplagiatus Dej. — Piceous, shining. Antennae, legs and oblique stripe 

 of elytra pale. Head very finely alutaceous. Thorax less than twice as wide 

 as long, slightly cordate, sides arcuate, sinuate near the hind angles which are 

 rectangular but not prominent, disc slightly convex, median line distinctly. 

 imj>ressed and entire, surface smooth. Elytra flat, oval, a little broader behind, 

 apex truncate, disc obsoletely striate at middle; the oblique pale vitta starts from 

 the humerus toward the suture and extends parallel with the latter beyond the 

 middle. Body beneath smooth, shining. Length .12 inch; 3 mm. 



Male. — Anterior tarsi with three joints slightly dilated, feebly lamellate beneath. 

 Anal segment slightly notched at middle, a single seta each side. 



Female. —Tarsi slender. Anal segment entire, one seta each side. 

 I fully agree with Dr. LeConte in uniting californicus with this 

 species. It affords another instance of the transcontinental distribution 

 of a species along our northern border. 



Occurs from the New England States to California. 



A. fusciceps Lee. — Yellowish testaceous, head piceous or nearly black. 

 Head finely alutaceous. Thorax about one-half wider than long, slightly nar- 

 rowed at base, sides moderately arcuate, somewhat sinuate in front of the hind 

 angles which are rectangular and slightly prominent, disc moderately convex, 

 median line impressed nearly entire, the subapical and antebasal transverse 

 impressions distinct, surface smooth. Elytra oval, a little wider behind, disc 

 slightly convex, vaguely substriate, more distinctly near the suture. Body be- 

 neath smooth, shining. Length .12 inch ; 3 mm. 



Sexual characters as above. 



As biplagiatus follows a complete line of transcontinental distribution 

 so this occurs over a shorter line extending from Texas to southern 

 California, following the line which Dr. LeConte has already noticed for 

 so many species which occur in the Peninsula of California. 



TECNOPHILU§ Chaud. 



The species referred to this genus were in times past placed in 

 Philotecnus until removed by Chaudoir, (Bull. Mosc. 1877, i, p. 240). 

 The latter genus is said to be identical with Cymindoidea. In the 

 present essay I will not attempt to determine 1 the value of the new genus 

 created for our species and will merely state that as far as a comparison 

 with our genera is concerned it is undoubtedly valid. 



The characters of the genus have already been referred to in the 

 preceding volume of these Transactions and sufficiently detailed figures 

 given of the mouth parts. There is no need, therefore, of repeating 

 here except to call attention to the fact that it is one of the few genera 

 of the tribe in our fauna with simple ungues.
