Famity—HISTERIDA. 
Grnus—TERAPUS. De Marseul. 
(Ann. Soc. Ent. de France, 4th Ser, tom. ii. 1862, p. 682.) 
Of this very anomalous Genus of Histeride, established by M. De Marseul upon the unique specimen in the 
Collection of Count Mniszech, the long legs with dilated tibiz, the large lateral expansions of the prothorax, 
the apparent want of a mesosternum (as in Scapiccelis), and the very wide insertion of the hind legs, are the 
most striking distinctions. 
Species 1—TERAPUS MNISZECHI. De Marseul. 
(Op. cit. p. 682, pl. X, gen. XLV, fig. 1.) 
‘Oblongus, postice gibbus, nigro-obscurus, clava antennarum tarsisque rufis, supra densissime punctatus, 
pilis rufis ; fronte concava stria brevi utrinque, clypeo angusto, margine elevato ; pronoto angulis anticis reflexis 
obtusis, margine incrassato, inciso, fossa utrinque unituberculata; elytris humeris gibbosis; propygidio basi 
ovatim atro-holosericeo, postice cireumpunctato bituberculato ; pygidio parum convexo basi punctato ; prosterno 
basi exciso, extus margine elevato, lobo lato punctato; mesosterno bisinuato ; tibiis anticis obtuse, intermediis 
acute extus angulatis, posticis contortis extus bituberculatis.’ 
Long. corp. 33 mill.; larg. 23 mull. 
Habitat; Mexico. In Mus. Com. Mniszech. 
Species 2—TERAPUS MARSEULII. Westw. 
Puate III, Fie. 9. 
Niger nitidissimus, minute punctatissimus ; pronoto angulis anticis rotundato-dilatatis, levissimis, dorso suleo 
lato profundo medio, angulis posticis elevatis, sulco transverso e parte antica separatis ; elytris breviter ovatis, 
sutura depressa, singuli medio disci elevato, podice sinuato; pedibus elongatis; tibiis omnibus extus pone 
medium angulatis, apice extus sulcatis pro receptione tarsorum recurvorum. 
Long. corp. lin. 2. 
Habitat; Amazonia (Bates). In Mus. Hopeiano Oxoniz. 
I have dedicated this curious insect to the indefatigable monographer of the Histeride. 
Genus—CHLAMYDOPSIS. Westw. 
(Trans. Ent. Soc. Lond. 1869, part iv. August, p. 318.) 
Genus Chlamydem habitu et Ectrephidem certo modo simulans; sed inter Byrrhidas (prasertim Murmi- 
dium, Leach = Ceutocerum, Schiipp.) et Histeridas intermedium. Corpus parvum, contractum, fere globosum ; 
pedibus contractilibus, contra latera corporis arcte applicatis ; prothorax antice profunde incisus pro receptione 
capitis; caput in prothorace fere omnino retractile (partes oris in individuis unicis haud examinatie) ; antenne 
9-articulatz, articulo primo magno subtrigono, septem proximis gracilibus, 4-8 minutis, nono (vel clava) pra- 
cedentibus sex longitudine quali vel longiore, exarticulato; elytra humeris valde gibbosis, gibbositate in 
medio intus luteo-setosa; metasternum maximum, coxis pedum posticorum haud prominulis; pedes sub- 
elongati, tibiis depressis pro receptione tarsorum simplicium et 5-articulatorum; abdomen segmento basali 
maximo.
