the description are not definite enough to enable one to separate it 

 with certainty from moraUis^ and it is likely that the Guadeloupe 

 example will be found to be the same as that species. Inasmuch as 

 Fauvel states that he had specimens of moratii^ and may be pre- 

 sumed to have compared them, I retain the species in our list 

 tentatively. 



I find no record of its habits. 



XVIII. Genus THORACOPHORUS Motschulsky 



Thoraxophorus MoTSCHm.sKY, 1837, pp. 98, 101 (error in transcription). 



Thoracophorus MorscHur.sKY, 1840, p. 197. 



Thoraxocophorus Kbaatz, 1858a, pp. 1047, 1048 (misspelling). 



Subgenus Stilbogastrus Bebnhaueb, 1908b, p. 286. 



Subgenus Lcipophorus Bernhauicb, 192Ga, p. 261. 



Genotypes. — T. corticinus Motschulsky (monobasic). Of Stilho- 

 gastrus, Thoracophorus nitidiis 'Bernhauer —Thoracophotvis {JStiJho- 

 oasfTUs) nilidii-fi Bernhauer (monobasic) ; of Leipophorus, 

 Thoracophorus {Leipophorus) minutissimus Bernhauer (designated 

 by Blackwelder, 1942). 



Diagnosis. — Body cylindrical ; head margined in front and at sides 

 above the eyes; gular sutures united; antennae short and stout; 

 mandibles very short; second segment of maxillary palpus much 

 enlarged, third wide but very short, fourth elongate but rather stout ; 

 head, pronotum, and elytra more or less costate; prosternum not 

 greatly prolonged; front coxae globose, cavities confluent, narrowly 

 open behind ; posterior coxae contiguous, ""'transverse" (not expanded 

 under the femur) ; abdomen not or very finely and indistinctly mar- 

 gined; sternites of first and second segments not present; tarsi 

 3-segmented. 



Remarks. — The genus named Glyptoma by Erichson was almost 

 exactly synonymous with Thoracophorus (as indicated by Erichson), 

 and five of the six original species are still placed in that genus. 

 Unfortunately, however, the first genotype designation was that of 

 Duponchel in 1841, in which he fixed the type as G. crassicorne 

 Erichson. This species is now placed in Calocerus.^ a\\^' Glyptoma is 

 therefore the same as that genus and takes precedence over it. 



The change of spelling by Motschulsky was justified by him as the 

 correction of an error in transcription, and as such is acceptable 

 under Article 19 of the International Rules. 



I have seen no examples of Erichson's two species from our region 

 and have therefore depended upon his descriptions for their char- 

 acters. One of them is quite distinct in certain characters from any 

 I have seen. 



The records of ThoracophoriLs rufcollis Fauvel from Guadeloupe 

 by Fleutiaux and Salle and by Leng and Mutchler are probably based
