1 , fig.- S. 



Entirely reddish yellow, tibiae and tarsi (except the claws) antennae 

 (except the basal joints) black. 



These few words will distinguish this species from any described in 

 our fauna. Specimens probably exist in cabinets with the recent manu- 

 script name jjedalis Lee. The females have all the tibiae black, in the 

 males the front tibiae are in part or entirely yellow. 



Occurs in Arizona. 



I... sanguineus Gorham, Biol. Cent. Am. vol. iii, pt. 2, p. 226. — Pale blood- 

 red, antennfe, tarsi and apical fourth of elytra black. Length 12-14 mm. % ; 

 18-20 mm. 9. 



In the female of this species the abdomen is more dilated 'than the 

 male and extends three-fourths the length of the elytra beyond their 

 apices. 



I found this species labeled L. posticus in Dr. LeConte's cabinet. It 

 has never been described by him. 



This species was collected by Morrison and sold to us as from Arizona, 

 and sent to Grorham as from Sonora. 



liYOISTOPTERUS Muls. 



li, laetus Gorham, loc. cit. p. 227, PI. xi, fig. 2. — Beneath blue-black; an- 

 tennae, disc of thorax at middle and tip of elytra narrowly, blue-black; elytra and 

 sides of thorax orange-red. Length 7-11 mm. 



This species is the one labeled by me as a Calochromus. The work 

 on this family has at all times been done by Dr. LeConte, and my notes 

 on his cabinet show that this species bears the manuscript name Lijgist.

l,¥€AIMA Duges. 



Ij. marginata Gorham, loc. cit. p. 209, PI. xii, fig. 8.— Piceous, sides of 

 thorax, lateral margin of elytra, anterior and middle femora orange-yellow. 

 Length 6-7 mm. 



'i'he disc of the elytra has somedmes a bluish tinge. This insect fig- 

 ures in Dr. LeConte's cabinet among the Lygistopteri under the name 

 of L. dehilis. Having given but little attention to this family any ex- 

 pression as to the validity of the genus proposed by Dug^s and accepted 

 by Grt)rham, would have but little value. 



(Collected in Arizona by Morrison.
