BYESOPOLIS.— PHALANGOGONIA. 291 



1. Byrsopolis lanigera. (Tab. XVII. fig. 2.) 



Castaneo-nitida, supra glabra, subtus cum pygidio et femoribus dense fulvo-hirta vel villosa : capite dense 

 aspere confluenter punctato ; clypeo sinuatim angustato, apice quadratim sublobato, reflexo, truncato ; 

 tborace quam elytra multo angustiore, lateribus regulariter areuatis, angulis posticis rotundatis, anticis 

 nullo modo productis, anguste marginato, margine basali medio subinterrupto, supra regulariter convexo, 

 confluenter disco sparsius punctato, interstitiis punctulatis linea irregulari dorsali laevi ; scutello breviter 

 cordato; elytris subtilius punctulatis, nitidis, costulis (vel striis geminatis) utrinque quatuor parum 

 distinctis ; pygidio parum convexo, dense piloso-punctulato. 



Long. 28 millim. 



Hab. Mexico (Salle, ex coll. Sturm). 



A single perfect example, bearing Sturm's label " Scarabceus laniger, mihi." 



2. Byrsopolis chihuahuae. 



Minus convexa, rufo-castanea, subtus sicut in S. lanigera fulvo-villosa, sed pygidio plus minusve senescenti ; 

 capite crebre aspere confluenter punctato; clypeo triangulari, lateribus leviter sinuatis, apice medio 

 acuminato-reflexo ; tborace multo minus convexo, margine paullo crassiore et magis reflexo omnino 

 integro, paullo post medium subangulatim dilatato, angulis posticis subrectis, anticis subacutis, supra 

 sicut in S. lanigera punctato ; scutello aeneo vel cupreo ; elytris grossius punctulatis, utrinque costulis 

 3 vel 4 distinctioribus cum striis punctatis geminatis impressis. (Tarsi omnes desunt.) 



Long. 26-28 millim. 



Hob. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn). 



Two imperfect examples. 



Subfam. ANOPLOGNATHINM 



PHALANGOGONIA. 



Phalangogonia, Burmeister, Handb. der Ent. iv. 1, p. 451 (1844). 



A genus, so far as at present known, peculiar to Mexico and Central America. 

 Three species have been described. 



l. Phalangogonia obesa. 



Phalangogonia obesa, Burm. Handb. der Ent. iv. 1, p. 452 \ 

 Hab. Mexico l , Chinantla (Salle). 



Burmeister mistook the example of this species on which he founded his genus for a 

 male, and hence gave erroneous characters to Phalangogonia and to the subfamily to 

 which it belongs. It was evidently a female, as the male has robust tarsi and claws, and 

 the anterior angles of the clypeus produced and dentiform, as in many of the Australian 

 Anoplognathinae. The three examples of the species in the Salle collection vary much 

 in colour, and one is a male. Besides the acutely-dentated angles, the arcuated fore 

 border of the clypeus is strongly reflexed ; and the robust major claw in all the tarsi is 

 not forked as in the male, nor properly speaking cleft, the upper part of the divided
