We have established a necessary and suficient condition for local solvability of a class of operators which are not elliptic precisely in a 1-dimensional submanifold and we construct solutions for a class of operators satisfying the condition (P) and which are not elliptic precisely in a point. / O presente trabalho estuda operadores diferenciais parciais lineares complexos de ordem um sem termos de ordem zero (campos de vetores complexos). Primeiramente apresentando uma condição necessária e suficiente para resolubilidade local de uma classe de operadores que deixam de ser elípticos precisamente em uma subvariedade 1-dimensional e por fim construindo soluções para uma classe de operadores que satisfazem a condição (P) e que deixam de ser elípticos precisamente em um ponto
