154 RHYNCHOPHORA. 
punctate; rostrum long, arcuate, not very slender, thickly punctate in its basal half, the apical half 
smoother; antennal club long, acuminate-ovate, the funiculus 6-jointed, 1 and 2 subequal in length. 
Prothorax broader than long, abruptly narrowed and tubulate in front, densely, finely punctate, the 
anterior margin raised, feebly emarginate, the lateral tubercles wanting, the base almost straight, the 
ocular lobes prominent. Elytra much wider than the prothorax, oblong-subquadrate, finely punctate- 
striate, the interstices densely rugulose, somewhat asperate towards the sides and apex. Femora 
unarmed. ‘Tarsal claws simple. 
Length 31, breadth 1-14 millim. ( 2.) 
Hab. Norva America, Parowan, Utah (Wickham).—Mextco (Truqui, in coll. Fry), 
Mexico City (H. H. Smith). 
Six specimens, the four from Utah (sent to me as an undescribed species by 
Mr. H. F. Wickham) with the legs almost entirely ferruginous. Following Dietz’s 
arrangement, the present insect belongs to the C. septentrionis-group, but it is very 
much larger than any of the eight forms enumerated by him. C. wickhami has some- 
what the facies of the much smaller European C. quercicola, Payk. It lives on a 
species of Argemone *, belonging to the order Papaveracee. 
2. Ceuthorrhynchidius aztecus, sp. n. 
Ovate, narrow, shining, nigro-piceous, the elytra reddish at the apex, the tip of the rostrum and the legs in 
great part ferruginous ; thickly clothed with small, oblong-ovate brownish and larger dirty-white scales, 
the brownish scales with a brassy lustre, the others condensed into a median line on the prothorax and 
an elongate scutellar patch on the elytra, the scales at the sides of the latter, like those on the under 
surface and legs, white. Head rugulosely punctate; rostrum moderately long, arcuate, striato-punctate, 
smoother at the tip; antennal club acuminate-ovate ; funiculus 6-jointed, 3 much shorter than 2, 
2 nearly as long as 1. Prothorax short, rounded at the sides, constricted and much narrowed in front, 
densely, finely punctate, the lateral tubercles small, the anterior margin truncate. Elytra oblong- 
subquadrate, finely punctate-striate, the interstices rugulose. Femora unarmed. Intermediate and 
posterior tibie feebly unguiculate at the inner apical angle. Tarsal claws simple. 
Length 14, breadth ;%, millim. (<¢.) 
Hab. Mexico, Mexico City (ZZ. H. Smith). 
One specimen. This minute insect belongs to Dietz’s C. septentrionis-group, but it 
cannot be identified with any of the species described by him. The scales on the 
prothorax have a brassy lustre, and those on the scutellar patch and at the sides of the 
elytra are rather large and oval. 
Group BARINA. 
Under this group are included the Ambatides, Péridinétides, Pantotélides, and 
Baridiides of Lacordaire, all of which have ascending mesothoracic epimeraf. The 
‘‘ Ambatides ” were widely separated from the Barina in his arrangement, on account of 
* A, mexicana is a common weed in Mexico and A. hispida inhabits both Utah and Northern Mexico 
(cf. Biol. Centr.-Am., Bot. i. p. 27). 
+ The 8.-American genera Bebelatus, Glycaria, and Enops, Pasc., are Cryptorrhynchids: Bebelatus comes 
near Xenosomus, Faust; Glycarta and Hnops belong to Conotrachelus in the wide sense, both having toothed 
tarsal claws and non-ascending mesothoracic epimera.
