AMERICAN COLEOPTERA. 151 



as long as the head and thorax, surface rather coarsely, densely and irregularly 

 punctured, sutural margin slightly elevated, lateral margin near apex subser- 

 rate. Body beneath shining, bluish, nearly smooth. Length .16 inch ; 4 mm. 



This species resembles the figure givea by Duval of the European 

 D. lineare. 



One specimen from Texas, given me by Mi-ss H. C. Cook of New 

 York City. 



L,ACTICA Erichs. 



This genus is introduced here to note the occurrence of two species 

 in our fauna. It is a part of the tribe Haltiddes as defined by Chapuis. 

 The antennae are approximate at base, eleven-jointed ; the claw joint 

 of the tarsi not inflated; the anterior coxal cavities open behind 

 and the thorax marked with a deep transverse impression in front 

 of the base. 



The two species are : 



Body above and beneath bright yellow, antennse (except at base), tibiee and 

 tarsi black ocreata. 



Head and thorax, anterior and middle legs yellow, elytra deep violet, body 

 beneath and hind l^gs black. specularis. 



L<. ocreata Say, {Aliica), Insects of Louisiana p. 7; Am. Ent. ed. Lee. i, 

 p. 303; xanthochroa Harold, Heft, xiii, 1875, p. 89.— " Body pale honey yellow; 

 antennae excej^ting the first and second joints, black; thorax on the posterior 

 submargin having a transverse groove, which does not reach the lateral margin, 

 but at its extremities it is abruptly reflected to the posterior edge; elytra 

 destitute of strise; feet with the knees, tibiae and tarsi black." Length .14— 

 -16 inch; 3.5 — 4 mm. 



I copy Say's description and add that : the anterior angles of the 

 thorax are obliquely truncate and subdentate as in certain Cri/pto- 

 phar/ua, and the elytra are sparsely irregularly punctate. 



Occurs from North Carolina to Louisiana. 



li. specnlaris Harold, Coleop. Heft, xiii, p. 89; xiv, p. 17.— Form and 

 sculpture of ocreata and differing in the characters given above. The anterior 

 angles of the thorax are not truncate. Length .14 inch; 3.5 mm. 



A very beautiful insect and apparently rare, as I have seen but the 

 one in my cabinet from Georgia. Harold's specimen is from Florida. 



ASIDA. Latr. 



.4. qnadricolliiii n. sp.— Black, shining. Head sparsely punctate. An- 

 tenna as long as the head and thorax. Thorax nearly square or a very little 

 wider than long, apex moderately deeply emarginate, base truncate, sides very 

 feebly arcuate, disc feebly convex, sparsely punctulate, margins slightly re- 

 flexed and coarsely subconfluently punctured, hind angles acutely recrangular. 

 Elytra a little wider at base than the thorax, margined for a short distance at 

 humeri, sides slightly divergent to the middle then rather rapidly narrowing 

 to tip, surface very sparsely punctate, disc feebly convex, suture sometimes
