242 ENTOMOLOGICAL NEWS. [December, 



This species has the general appearance of geiiiilis, but is 

 unique in the character of its sculpturing. 



Blapstinns Goronadensis n. sp. — Length, males 4.6-5.6 mm.; females 5- 

 6.3 nun.; width ^ 2-5 mm.; 9 2.8 mm. Form elongate oblong; color 

 black, legs and antennae rufo-piceous ; surface polished ; pubescence 

 evenly distributed, conspicuous, rather long, recumbent, pale flavate. 

 Head feebly transverse, moderately finely densely punctured; epistonia 

 narrowly and deeply sinuate; eyes moderate, rounded; antenna; rather 

 slender, moderately incrassate in last four joints. Prothorax moderately 

 convex, about a third wider than long; apex feebly emarginate in circular 

 arc, angles slightly acute; sides subparallel in posterior third and thence 

 to apex rather strongly arcuate; base transverse, lateral sinuations feeble, 

 angles right; disc moderately finely, densely and evenly punctured, basal 

 impressions just perceptible. Elytra about two and a half times longer 

 than prothorax, sides subparallel, very- feebly arcuate to posterior third, 

 then rather evenly and strongly to apex, which is rounded; base trans- 

 verse, not perceptibly wider than contiguous base of prothorax; disc 

 finely striate, striae very feebly impressed, finely and regularly punctured, 

 intervals just visibly convex, extremely finely punctured; scutellum bright. 

 Abdomen finely and sparsely punctured; legs moderate, femora rather 

 robust. 



Male. — Anterior and middle tarsi dilated, but not as strongly as in ru- 

 fipes. Eyes larger; abdomen feebly impressed in middle towards base; 

 head shorter and more transverse. 



Described from a male and female, supplemented by a series 

 of one hundred specimens. A distinct species and readily dis- 

 tinguished from rufipes by having well-developed wings, which 

 are about one-third longer than the elytra, the smooth and pol- 

 ished surface, denser pubescence, finer punctuation, nearly flat 

 elytral intervals, darker legs and less dilated tarsi. The pubes- 

 cence is very readily removed by slight friction, and cabinet speci- 

 mens are generally quite denuded. The species is diurnal. Fre- 

 quents garbage heaps during May and June. 



I have carefully compared the above series with a large series 

 of rufipes and found no intergrading of alar development. On 

 the other hand, there was a wonderful constancy in the form and 

 size of the rudimentary hind wings in tl\e latter species, agreeing 

 in details with the description given by Thos. L. Casey in his 

 " Coleopterological Notices," p. 440. 



Careful examination of a large series of riifipes demonstrates 

 that the elytral intervals may be decidedly convex, and always 

 more so than in Coronaderisis. The former species is often quite 

 pruinose when captured, and this I have never observed in the 

 latter.
