new Coleoptera from McdeUln. 427 



anterior part of its inner margin is marked by a well developed 

 obtuse triangular tootli.* Thorax a very little (one-seventli) 

 longer than broad, very slightly convex, constricted at the apex, 

 narrowed before the middle, gently arcuate at the sides, the 

 broadest part a little before the base, with a few large punctures 

 in the middle near the base, red, with five large black spots, one 

 discoidal anterior, one at each anterior angle, and a triangular 

 one on each side of the base. Elytra at the shoulders very little 

 broader than the thorax, gradually (but not much) narrowed 

 towards the apex, rather deeply striated, the strias distinctly but 

 not very closely punctured, interstices very slightly convex, dull 

 red, with a black spot common to both elytra at the scutellum 

 and another at the apex, each elytron has also three rather large 

 black spots, one just within the shoulder, another in the middle 

 near the suture, and a third near the apex extending from the 

 fourth stria to the margin. There are a few rather large piuic- 

 tures scattered on the middle and sides of the prosternum; the 

 metasternum is very strongly punctured at the sides, the middle 

 portion as well as the middle of the first and second abdominal 

 segments are broadly and rather strongly im2:)ressed; the sides of 

 the abdomen and the apical segment are strongly punctured. 

 Legs smooth, the middle of the femora and tibia; pitchy-red; 

 the tibiaj have the inner apical half sinuate, especially the four 

 posterior in which the commencement of the sinuatiou is marked 

 by a tuft of stiff hair. 



HISPIDiE. 



Arescns Icevicollis, n. sp. 



Flavus, nitidus; capite lajvi, f route canaliculata, antennis 

 nigris, articulis tribus basalibus subtus flavis; thorace paulo 

 transverso, lajvi, angulis anticis cxtus leviter sinuatis, laterihus 

 rectis, posticis acutis ; scutello cyaneo-nigro ; elytris striato- 

 punctatis macula humerali dimidioque apicali cyaneo-nigris; 

 tarsis tiblisque anticis nigris. Long. h\ lin. 



Close to A. luliatns, which it resembles in form, but, besides a 

 coloration which I have not met Avith in any varieties of that 

 species, it differs in having the thorax entirely destitute of piuic- 

 tures, the inter-antennal ])roduction of the head is In-oader and 

 truncate at the apex. The sutural angle of the elytra has a 

 small ()l)li([Ue truncature without any tooth at the sutm-e. 



* Something- similar is seen in some other species oi' this j,'-enus, hut 

 I Iiave not seen any in which it is so pronounced.
